Specifications Ceramic Capacitor: Ceramic COG (NPO) - Ceramic COG (NPO) capacitors have a high Q, low K, temperature-compensated dielectric and stable electrical properties under varying voltage, temperature, frequency and time. They are suitable for low-lost circuits and for timing and tuning applications. There are several unofficial, colloquial temperature coefficient designations for capacitors. The temperature coefficient is given as P for positive and N for negative, followed by a 3-digit value in ppm/°C. For example, P100 is +100 ppm/°C and N220 is -200 ppm/°C. The exception to this system is NPO where the letter "O" instead of the number "0" is used; however, the term NP0 is not uncommon. Both NPO and NP0 indicate that the capacitor is stable with temperature. Ceramic X7R - Ceramic X7R (BX) capacitors have moderate K values and are temperature-stable. They exhibit moderate changes in electrical properties under conditions of changing temperature, voltage, and frequency. X7R capacitors are suitable for bypass, coupling, and frequency discrimination circuit applications. X7R capacitors exhibit no more than 15% capacitance deviation over a -55 °C to +125 °C temperature range. Ceramic Z5U - Ceramic Z5U capacitors are Class III devices with a dielectric that exhibits a maximum capacitance change of +22% - 56% over an operating temperature range of +10 °C to + 85 °C.

Wed, 20 Aug 2008 04:02:00 GMT http://suntan-capacitors.spoonylife.com/fused-tantalum-capacitor-28721.html AVX's TAW series of fused tantalum capacitor protect against damaging high DC leakage currents at high currents. Short circuit failure mode protection is accomplished using an internal fuse connected in series with the capacitor. When the fuse exceeds its current limit, the fused capacitor will fail safe by effectively removing itself from the circuit by creating a high resistance path of above 10MΩ. In some cases this can mean the difference between a total circuit loss and barely detectible performance degradation. The TAW series tantalum capacitors are fully lead-free and RoHS compliant. Wed, 20 Aug 2008 03:59:00 GMT http://suntan-capacitors.spoonylife.com/tantalum-capacitor-informations-ii-27273.html This November, our company will attend Electronica2008 in Munich, Germany. At this fair, we will strongly recommend our Tantalum Capacitor to visitors and customers from all over the world. Especially TS19 Dipped Tantalum Capacitor and and TS20 Chip Tantalum Capacitor will be our focus. From the sales performance of 2008 first half year, the two Tantalum Capacitors bring us very good business and customers' comment to the two series is satisfactory , these bring us more confidence to expand our market for Tantalum Capacitors all over the world, especially in Europe and in America. The lead spacing and form outline are very important in selecting your choice of dipped tantalum capacitor. Lead spacing is determined is offered in a few common spreads. They are indicated in the chart below. There are some common outline forms used by the leading manufacturers of dipped radial tantalum capacitors. Some of these have names such as "hairpin" "hockey-stick" and "lock-in". These are determined by the type of crimps in the leads. These capacitors are made to specific case sizes. Some manufacturers offer a wider selection than others. For example AVX offers their TAP series of dipped radial tantalum capacitors in 15 case sizes while Sprague/Vishay offers their comparable 199D series in 6 sizes. Since a dipped radial tantalum capacitor is polarized it is important to understand how these units are marked to ensure that they are inserted properly into the circuit. We have included charts they will show you how some of the leading manufacturers mark this style of capacitor along with the most common lead forms. Some applications where you can use a dipped tantalum capacitor are bypassing, coupling, blocking, filtering and timing in wide range of commercial, industrial and military applications. Other types of capacitors that can be used for these applications are ceramic and film capacitors. Each dielectric has advantages and disadvantages. The tantalum advantages are higher capacitance values within a given package size and stability of capacitance with applied DC voltage. Tantalum capacitors are a form of electrolytic capacitor. However, some forms of them are non-polar, containing two capacitors connected in series (negative to negative). In comparison with aluminium electrolytic capacitors, they are for similar capacitance and volume ratings generally more expensive, with lower effective series resistance. They usually have longer life, especially at moderately elevated temperatures. For surface mount devices, they are generally smaller. Tantalums exploit the tendency of tantalum to form a protective oxide surface layer. They use tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor with the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, Tantalum Capacitor is useful in portable telephones, pagers, personal computers, and automotive electronics. Wed, 13 Aug 2008 10:46:00 GMT http://suntan-capacitors.spoonylife.com/ceramic-capacitor-informations-iii-27270.html The multilayer ceramic capacitor has a many-layered dielectric. These capacitors are small in size, and have good temperature and frequency characteristics.This capacitor is used to bypass the high frequency to ground, Above about the Multilayer Ceramic Capacitor information content. We offer these Disc Ceramic capacitor in a wide range of voltages and capacitance. They are Radial Lead type. Ceramic capacitors are used for blocking, by-pass and coupling of DC and signals to VHF range, pulse logic and timing circuits and for general purpose applications. Choose NP0 type when stability is of concern, such as in RF circuits. The monolythic ceramic are epoxy dipped. They are small in size and are used in VHF circuits, bypassing, and general purpose use. They are preferred over standard Ceramic capacitor for their small size and stability. The photo to the right both show a .1µf value at 50 volts. You can clearly see the size difference. Ceramic capacitors are constructed with materials such as titanium acid barium used as the dielectric. Internally, these capacitors are not constructed as a coil, so they can be used in high frequency applications. Typically, they are used in circuits which bypass high frequency signals to ground. These Ceramic capacitors have the shape of a disk. Their capacitance is comparatively small, Above about the Ceramic Capacitor information content. The Ceramic capacitor on the left is a 100pF capacitor with a diameter of about 3 mm. The Ceramic capacitor on the right side is printed with 103, so 10 x 103pF becomes 0.01 µF. The diameter of the disk is about 6 mm. Ceramic capacitors have no polarity. Ceramic capacitors should not be used for analog circuits, because they can distort the signal.

These capacitors are small in size, and have good temperature and frequency characteristics.This capacitor is used to bypass the high frequency to ground, Above about the Multilayer Ceramic Capacitor information content. Ceramic capacitor offer a broad range of size vs. performance tradeoffs and are easily the most popular in numbers sold. Ceramic capacitors are available from Ceramic capacitor are their relatively high dielectric constants. This can vary from C0G with a K of up to 60, which has excellent electrical properties but is relatively large and expensive, to ceramics with Ks in the tens of thousands but with very poor electrical properties. Large- value ceramics can replace electrolytic capacitors in high-frequency applications like switch-mode power supplies because of their lower ESR. Ceramic capacitors are especially suitable for surface mounting due to their heat resistance, mechanical integrity, and the ability to make them in very small packages at low cost, for portable equipment. This has greatly added to their usage. To some extent ceramics are slowly displacing other types of capacitors. Cons: Low breakdown voltage means that the low-K ceramics (Class 1), the ones with the good electrical properties, have poor volumetric efficiency, and are usually found only in small values. High-K ceramics (Class 2 and higher) have poor electrical properties, which are highly dependent on temperature, voltage, and frequency, plus a significant aging rate. Unlike many other capacitors, ceramics have no self-healing mechanism. This means that manufacturers must maintain a high level of quality control over the dielectric. Ceramics are most cost affective in small sizes at present. Very large ceramics are a bit of a challenge, especially in SMD.

Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors). Ceramic Capacitor Knowledge A ceramic capacitor is a two-terminal, non-polar device. The classical ceramic capacitor is the "disc capacitor". This device pre-dates the transistor and was used extensively in vacuum-tube equipment (e.g., radio receivers) from c.a 1930 through the 1950s, and in discrete transistor equipment from the 1950s through the 1980s. As of 2007, ceramic disc capacitors are in widespread use in electronic equipment, providing high capacity et small size at low price compared to other low value capacitor types.

Fri, 01 Aug 2008 16:50:00 GMT http://suntan-capacitors.spoonylife.com/tantalum-capacitor-suppliers-still-wary-about-ability-to-meet-demand-23138.html Component makers are cautiously optimistic that unit demand for Tantalum Capacitor will remain strong this year, which could result in a tight supply of these devices in the second half of 2001. Contributing to the problem is a shortage of raw materials that became apparent at the end of 2000. Although supply for Tantalum Capacitor in smaller package sizes such as A and B is more in line with demand, larger C, D and E(X) sizes are still in short supply, say passive-component suppliers. "Supply for A, B and P case sizes has loosened up dramatically due to lower demand from cell-phone manufacturers," said Rich Schuster, the president of NIC Components Corp. (Melville, N.Y.). "They're probably off allocation." Schuster said lead times for Tantalum Capacitor in A- and P-case sizes have dropped to eight to 10 weeks, while deliveries for devices in B-size packages are a little longer at 10 to 12 weeks. Devices in the B-case size are used in a variety of applications in the telecom and PC sectors. The larger case sizes are still in short supply, primarily because of limited production capacity. During last year's shortage many capacitor manufacturers, particularly in Japan, shifted most of their production to the smaller packages to meet explosive demand in the cell-phone and handheld-device markets. Demand for the larger tantalum capacitors is still pretty high, Schuster said. These devices are used in consumer, industrial, PC, peripheral and telecommunications applications-and are still on allocation, he said. "Most of our production capacity for tantalum capacitors has been on allocation to our strategic customers for this year and that will remain so until we get a better feel for where the market is headed," said Glyndwr Smith, assistant to the CEO and senior vice president at Vishay Intertechnology Inc. (Malvern, Pa.). Smith said demand will depend on several factors, including the overall economy, inventory-adjustment time frames and growth in key end markets in 2001. Mike Morton, senior vice president of product marketing for passive-component manufacturer TTI Inc. (Fort Worth, Texas), said he believes the industry will start to see improved availability for the larger D- and E-case sizes in the second quarter. However, a key challenge Tantalum Capacitor manufacturers face is a shortage of the tantalum powder needed to produce the parts, particularly for the larger devices that consume more raw materials, said Eric Pratt, director of information services at iSuppli Corp. (El Segundo, Calif.). Strong demand for tantalum capacitors has severely strained the supply of capacitor-grade tantalum powders. The production of tantalum powder to manufacture tantalum capacitors represents about 60 percent of the overall consumption of tantalum, according to materials supplier H.C. Starck Inc. (Newton, Mass.). Until additional tantalum-ore production capacity comes online in the middle of 2001, supply will remain tight, materials suppliers and component manufacturers agreed. In addition to shortages, the tight supply of materials has produced price hikes, which in some cases are being passed on to the customer. For instance, NIC Components has recently increased prices between 10 and 15 percent and anticipates an additional price hike in April. Although the component market appears to be in the midst of an inventory adjustment period and a general slowdown from key industry sectors, capacitor makers predict that won't last long and are in fact preparing for severe shortages of Tantalum Capacitor by the second half of 2001. To meet customer requirements, some cap makers have formed partnerships with materials producers to establish independent supply sources of tantalum to meet their increased demand. Kemet Corp., for instance, has established a 50/50 joint venture with Australasian Gold Mines NL to own and fund the development of existing Australasian tantalum projects, including the pilot plant at Dalgaranga, Australia. It also provides for the purchase of processed tantalum products by Kemet from the pilot plant and other processing entities. Thu, 31 Jul 2008 17:37:00 GMT
