About Multilayer ceramic capacitor

Ceramic capacitors are known to comprise alternating layers of inner electrodes and ceramic dielectrics. A laminated Ceramic capacitor includes a laminate formed of a plurality of laminated dielectric ceramic layers and an internal electrode laminated therein. Monolithic ceramic capacitors have a rectangular shape, and are provided with external electrodes at the opposite ends thereof, respectively. The development of integrated circuits has made it possible to place many circuit elements in a single semiconductor chip. A multilayer Ceramic capacitor has been used widely as a compact, high power, and highly reliable electronic part and employed in a large number of electronic circuits. The multilayer ceramic capacitor comprises a layered dielectric body composed by alternately laminating dielectric layers and inner electrode layers and terminal electrodes formed on the main body of the layered dielectric element. The ceramic layers are stacked together in a manner that the internal electrodes are alternately exposed at opposite sides of the laminated body. The external electrodes are disposed at the end portions including the opposite sides of the laminated body and are connected to respective sets of internal electrodes of the laminated body.  

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 Capacitors information content.

In the photograph, the capacitance of the component on the left is displayed as 104. So, the capacitance is 10 x 104 pF = 0.1 µF. The thickness is 2 mm, the height is 3 mm, the width is 4 mm.
The Multilayer Ceramic Capacitor to the right has a capacitance of 103 (10 x 103 pF = 0.01 µF). The height is 4 mm, the diameter of the round part is 2 mm.These Multilayer Ceramic Capacitors are not polarized. That is, they have no polarity, Above about the Multilayer Ceramic capacitors information content.
