Mica Capacitors

Mica capacitors are used in applications where high degrees of precision, stability and reliability are required. They are commonly found in high-frequency applications as they have qualities that allow them to provide low loss and low capacitor change-over time.
The mica capacitor is made from sheets of mica that have been coated with deposited metal on both sides and then dipped in epoxy to protect it from the environment. Mica minerals are electrically, chemically and mechanically stable.
Types of Mica Capacitors
There are several types of mica capacitors available depending on the form factor, voltage, capacitance range and lead spacing required.
• Standard dipped
• Reel packed dipped
• SMT multilayer RF chip
• Miniature dipped
• High reliability dipped
• SMT multilayer RF clad
• High voltage
• SMT multilayer PTFE
• High frequency dipped mica
Mica capacitors can be found in a wide range of applications including:
• Resonance, time constant, coupling and high-voltage inverter circuits
• Cable TV and radio transmitters
• Defence electronics
• Aerospace
• Medical
