Exxelia offers four product series of mica capacitors:
The CMR series built to MIL-PRF-39001 standards, exemplifies precision and reliability. Ideal for RF applications, these silvered mica capacitors deliver a high Q factor, ensuring minimal energy loss and consistent performance even under extreme conditions, with a capacitance range from 1 pF to 12,000 pF and voltage ratings up to 500 V. Operating across a temperature span of -55° C to 150° C, they are engineered for environments where performance is non-negotiable.
For applications requiring robust endurance at elevated temperatures, the CM series is the go-to choice. Designed to operate up to 150° C and conforming to MIL-C-5 standards, these capacitors combine exceptional thermal stability with capacitance values between 200 pF and 12,000 pF and voltage ratings up to 500 V. Their low dielectric losses make them indispensable in sectors like aerospace and military, where resilience in harsh environments is crucial.
Complementing these ranges is the MF series, a high-reliability solution crafted for precision in critical applications. With capacitance values spanning from 4.7 pF to 33 nF and voltage ratings up to 1 kV, these dipped mica capacitors deliver excellent temperature stability and high Q performance, particularly suited for RF systems and sensitive instrumentation. Their compact design and reliable performance make them a trusted choice for precision-oriented technologies.
The CA series rounds out the offering with its superior capabilities in high-rel applications. Featuring capacitance values from 0.005 nF to 0.1 µF and voltage ratings up to 1 kV, these silvered mica capacitors excel in RF and microwave applications. Operating within a temperature range of -55° C to 125° C, they combine a high Q factor and low equivalent series resistance (ESR) to deliver exceptional performance and minimal energy loss in the most demanding conditions.
These four series demonstrate the versatility and durability of mica capacitors, providing customized solutions for a broad spectrum of critical applications across industries that demand the highest levels of precision and reliability.
