CDV30EK470FO3

Mica and Polytetrafluoroethylene (PTFE) capacitors are reliable, high-performance components used in a wide range of electronics applications. The CDV30EK470FO3 is a prime example, offering high capacitance and low effective temperature drift. It is mainly used as a resonant circuit element in AC circuits.

Applications

The CDV30EK470FO3 mica capacitor is a trusted component used in a wide variety of electronic devices. Its anode and cathode electrodes and the mica dielectric layer offer a superior combination of characteristics for filter and resonant circuits that must operate in electrical environments with high temperatures and voltage variations. It is widely used to improve noise cancelling, stability, and reduce microchips electromagnetic interference (EMI). Other common applications include transistors, switching power-supplies, low noise amplifiers, CRT television and monitor circuits, and in precision audio circuits.

Working Principle

Mica and PTFE capacitors are constructed of two metal plate electrodes and a mica dielectric layer between them. When a voltage is applied across the mica dielectric, an electrical field is created in the layer that causes the metal plates to be attracted closer together reducing the capacitance of the capacitor. This effect is also known as dielectric absorption. The CDV30EK470FO3 is known for its low absorption characteristics which make it suitable for use in high temperature environments. In such cases, the capacitance value remains the same even when the temperature increases; a valuable ability for precision circuits.

The low dielectric absorption also makes the CDV30EK470FO3 a popular choice for high frequency applications, such as in RF transmitters, allowing for higher performance than standard capacitors. Another feature of note is its low effective temperature drift; that is, its capacitance value does not substantially change as the temperatures vary.

Conclusion

The CDV30EK470FO3 capacitor is a high-quality mica and PTFE component with a reliable, high-performance combination of characteristics. It offers low absorption, low effective temperature drift, and can handle voltage variations and temperatures as high as 125 degrees Celsius, making it an ideal choice for a wide variety of high frequency, filter and resonant applications.
