More Information About Mica Capacitors

What is a Mica Capacitor?

Mica capacitors, also known as silver mica capacitors, are capacitors that offer high precision, reliability and stability. They are available in small values and are generally used at high frequencies and in situations where low losses and low capacitor change over time are required. A mica capacitor is assembled from sheets of mica that are coated with deposited metal on both sides. The assembly is then dipped in epoxy.

Types of Mica Capacitors

There are many different kinds of mica capacitors. At Future Electronics we stock many of the most common types categorized by rated voltage, tolerance, lead spacing, packaging type and capacitance. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common values for capacitance are 22 pF, 47 pF, 100 pF and 470 pF. We also carry mica capacitors with capacitance up to 10000 pF. The rated voltage can be between 50 V and 1 kV, with the most common capacitors having a rated voltage of 500 V.
