Mica and PTFE Capacitors

CMR03C2R5DOCM Application Field and Working Principle

Mica and PTFE capacitors are becoming increasingly popular in consumer electronics and industrial applications due to their reliable performance, good physical properties, and high frequency response. The CMR03C2R5DOCM, made by Cornell Dubilier, is a ceramic, mica-based capacitor with two capacitors connected in series. It is rated for 3.5 KV AC and 0.5 KV DC and offers excellent high frequency response, making it ideal for power supplies and RF circuits.

In order to understand how the CMR03C2R5DOCM works, we must first understand the nature of electric capacitance and how capacitors store energy. All capacitors are composed of two metal plates separated by an insulating material, the dielectric. In the CMR03C2R5DOCM, the dielectric is made of mica, which is highly efficient at storing electrical energy. When an electrical charge is applied to the plates, a potential difference is created. This potential difference allows the capacitor to store and release energy very quickly, making this capacitor ideal for high-frequency applications.

The CMR03C2R5DOCM capacitor offers excellent performance for various applications. Its relatively low losses offer great power factor characteristics, making it an excellent choice for power supplies. In addition, its low inductance makes it a great high-frequency component, while its low parasitic reactance makes it ideal for RF circuits. The CMR03C2R5DOCM is also rated for operation up to 125°C, making it suitable for industrial applications.

The CMR03C2R5DOCM is also widely used in consumer electronics. Its fast settling time and low losses make it a great choice for audio circuits, allowing for lower distortions and better sound quality. Its excellent audio performance also makes it ideal for microphones and noise-cancelling applications.

In summary, the CMR03C2R5DOCM is a versatile capacitor that can be used in a wide variety of applications. Its low inductance and high-frequency response make it ideal for power supplies and RF circuits, while its fast settle time and low losses make it great for consumer electronics. Its excellent heat dissipation and temperature stability make it suitable for industrial applications.
