High-performance mica capacitors deliver for critical applications

Exxelia offers four series of mica capacitors, tailored to meet the stringent demands of RF, defence and aerospace applications. Mica capacitors are valued for stability and reliable performance across a wide range of applications. They maintain consistent electrical characteristics over time and across temperature variations, making them appropriate for use in critical environments.

The company's silver mica capacitors were developed to offer performance, stability, precision and reliability, and include series designed as per MIL standards. They supply a high Q factor that decreases energy loss, improving efficiency, particularly in RF applications. These capacitors are designed to withstand demanding conditions, supporting voltage ratings up to 1kVDC and operating temperatures up to +150C. Besides, it offers custom design options and ensures long-term product availability without obsolescence.

The company offers four products series of mica capacitors:

The CMR series built to MIL-PRF-39001 standards, exemplifies precision and reliability. Excellent 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 500V. Operating across a temperature span of -55C to +150C, they are engineered for environments where performance is non-negotiable.

For applications demanding robust endurance at elevated temperatures, the CM series is the optimal 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 200pF and 12,000pF and voltage ratings up to 500V. The low dielectric losses make them indispensable in sectors like aerospace and defence, where resilience in harsh environments is crucial.

Complementing these ranges is the MF series, a high-reliability solution developed for precision in critical applications. With capacitance values spanning from 4.7pF to 33nF and voltage ratings up to 1kV, these dipped mica capacitors supply excellent temperature stability and high Q performance, particularly suited to RF systems and sensitive instrumentation. The 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. Offering capacitance values from 0.005nF to 0.1µF and voltage ratings up to 1kV, these silvered mica capacitors excel in RF and microwave applications. Operating within a temperature range of -55C to +125C, they combine a high Q factor and low ESR to deliver outstanding performance and minimal energy loss in the most demanding conditions.

These four series demonstrate the versatility and durability of mica capacitors, providing customised solutions for a wide spectrum of critical applications across industries that demand the highest levels of precision and reliability.
