CDV30FK121FO3

Mica and PTFE Capacitors

CDV30FK121FO3 is a capacitor in the Mica and Polytetrafluoroethylene (PTFE) Capacitors category. It is an electronic component designed to store and discharge electrical energy consistently. Mica and PTFE capacitors are used in a number of commercial and industrial applications due to their combination of features and affordability.

Application Field

In general, Mica and PTFE capacitors are used in audio equipment, controlling circuitry, test/measurement circuits, and power supplies where high reliability is paramount. Additionally, their superior stability, reliability, and long life under extreme temperature and voltage conditions also make CDV30FK121FO3 ideal for certain applications.

CDV30FK121FO3 specifically is used in industrial electronics and telecommunications. It generally consists of a polyimide-based dielectric, PTFE-based dielectric, and a thin metal membrane. It has high temperature and humidity limits as well as superb heat rejection capabilities. These features make it ideal for high-vibration environments. It is also well-suited for high-precision, high-frequency applications, such as video signal generation and transmission.

Working Principle

The primary function of a capacitor, and thus CDV30FK121FO3, is to store an electrical charge. When a voltage is applied to the capacitor’s terminals, it will absorb the energy and store it in the form of an electric field in the dielectric material, where the voltage remains until it is released. This is the basis of all capacitors and CDV30FK121FO3 is no exception.

The specific working principle of CDV30FK121FO3 is that the capacitor is composed of two metal plates, separated by a dielectric insulator. When a voltage is applied, a dielectric is created between the plates and the electric field. As the voltage increases, the electric field increases until it is equal to the applied voltage. The electric field then remains constant until the applied voltage reduces or the device is discharged.

The combination of a polyimide-based dielectric and PTFE-based dielectric in CDV30FK121FO3 gives it superior performance compared to typical capacitors in terms of resistance to temperature fluctuations and mechanical vibrations. This makes CDV30FK121FO3 ideal for high-precision, high-reliability, and long-term applications.
