Mica and PTFE Capacitors

Mica and PTFE capacitors, or Plate Capacitors, are widely used in all kinds of electronic circuits, from AC-DC power converters to home automation appliances, to name only a few. Their working principle and application field are closely related, so let\'s take a closer look at these components.

CMR04E470JPDP

CMR04E470JPDP is a Plate Capacitor made of Microwave Ceramic and PTFE. It is a radial-type component with two terminals at the end of the electrode plate, and its electrical characteristics are as follows:- Rated voltage: 250V- Rated capacitance: 470pF- Dissipation factor: 0.15- Frequency range: 1kHz-2.5GHz- Temperature coefficient: -400ppm/°C

Application Field

CMR04E470JPDP is a wide-band capacitor designed for high-frequency applications. It can be used in filters, radio frequency (RF) circuit designs, power-supply circuits, and other electronic circuits requiring precise capacitance values.

Working Principle

The working principle of CMR04E470JPDP is simple: the capacitance provided by the capacitor is a function of the distance between the two communication plates. The PTFE serves as the dielectric and provides an adjustable capacitance, while the Microwave ceramic provides a high frequency range.The PTFE is a very reliable dielectric material and is able to withstand a wide range of temperatures and has excellent electrical insulation properties. It also provides good environmental stability.The Microwave ceramic offers excellent electrical insulation properties and is able to withstand temperatures up to 270°C. It also provides high frequency stability. In addition, its frequency range makes it ideal for use in RF and microwave applications.The combination of these two materials gives CMR04E470JPDP its special characteristics. It is able to withstand high temperature ranges and to offer high frequency stability, and it also has excellent electrical insulation properties. This makes it ideal for high-frequency applications such as filters, radio frequency (RF) circuit designs, and power supplies, allowing for precise capacitance values.

Conclusion

Mica and PTFE capacitors, such as CMR04E470JPDP, are widely used in all kinds of electronic circuits due to their excellent electrical insulation properties, high frequency stability, and ability to withstand temperatures up to 270°C. Their working principle is based on the distance between the two communication plates, where the PTFE serves as the dielectric and provides an adjustable capacitance. This makes it ideal for high-frequency applications such as filters, radio frequency (RF) circuit designs, and power supplies.
