Mica capacitors

In terms of structure, it can be divided into foil type and silver type. The silver electrode is directly on the mica with vacuum evaporation method or sintered by silver coating, due to eliminating the air gap, the temperature coefficient decreased significantly, the stability of the capacitor is also higher than the foil type.

Good frequency characteristics, high Q value and small temperature coefficient

Can not make a big capacity

   Widely used in high-frequency electrical appliances, and can be used as a standard capacitor
