MISCELLANEOUS DIELECTRICS

Miscellaneous capacitors include materials like glass, mica, porcelain, and even gas and vacuum.  A few exotic dielectrics like silicon dioxide and sapphire are used in niche applications like microwave capacitors and trimmers.  Some are available in surface-mount packages.

Pros:  The electrical properties of the miscellaneous capacitors are generally most similar to film capacitors.  However, they all have electrical properties that make them useful in some special applications.

Cons:  These materials also have Ks similar to plastic films so they have no advantage in size.  Except for mica, these capacitors are commonly available only in small sizes, <1 uF.  They also tend to be more expensive than other capacitors of similar size.
