Mica and PTFE Capacitors: CMR03E330GOYM application field and working principle

Introduction

Mica and PTFE capacitors, also called mica-filled PTFE capacitors, are a type of high-reliability capacitor that use PTFE (polytetrafluoroethylene) as the dielectric, and mica as the reinforcement. The mica provides additional protection against environmental degradation and helps to maintain structural integrity and supports the electrical field. Mica and PTFE capacitors are mostly used in military, aerospace, and medical applications for their superior performance and reliability. The CMR03E330GOYM is one such mica and PTFE circuit capacitor, manufactured by AVX Corporation.

Application fields

The CMR03E330GOYM is a special type of mica and PTFE capacitor designed and optimized for operations in high-frequency and high-temperature applications. It is particularly suitable for communications equipment, radar systems, and ultra-high frequency communication systems, as it provides improved electrical performance and higher reliability under severe environmental conditions. The CMR03E330GOYM has a wide range of operational temperature, from -55°C to + 165°C. It is also characterized by a very low equivalent series resistance (ESR) and low self-heating. This makes it particularly suitable for high-power, high-efficiency power electronics systems, such as DC-DC and AC-DC converters, motor control systems, and high-frequency power supplies.

Working principle

The CMR03E330GOYM capacitor consists of a metalized polytetrafluoroethylene (PTFE) dielectric layer between two metallic layers, which are separated by a thin mica sheet. At the heart of this capacitor is a high-temperature resistant, class-A dielectric (HTR-A) material that guarantees stable electrical performance even under large temperature variations and wide temperature range. The voltage rating of the CMR03E330GOYM is 10V.The capacitor works by storing electrical charge in the PTFE layer, and then releasing it in the form of an electrical current when an alternating current is introduced. The mica layer acts as an insulating barrier between the PTFE dielectric layer and the conducting metal layer. The metal layer ensures that the charge is not released too quickly. The capacitor also has excellent electrical characteristics, such as high dielectric strength, low inductance, and high capacitance, which make it suitable for high frequency applications.

Conclusion

The CMR03E330GOYM is a special type of mica and PTFE capacitor designed specifically for high-performance, high-frequency, and high-temperature applications. It is widely used in communications equipment, radar systems, and ultra-high frequency communication systems, and other power electronic systems due to its high capacitance, low ESR, and low self-heating. It consists of a metalized polytetrafluoroethylene (PTFE) dielectric layer between two metallic layers, with a thin mica sheet acting as an insulating barrier. The capacitor works by storing electrical charge in the PTFE layer and then releasing it as an electrical current when an alternating current is introduced.
