BFC233864473

Film Capacitors

The BFC233864473 is a type of film capacitor typically used to filter or decouple signals in circuits with frequencies up to 1 MHz.

Application field

The BFC233864473 film capacitor is mostly used for safety applications. Film capacitors are used to absorb signal over-voltage and act as a transient voltage suppressor for industrial and consumer applications. As a safety feature, it can also protect the circuit from Circuit breaker or fuse failures.

The BFC233864473 film capacitor can also be used as a bypass capacitor for low/high frequency ripple filtering. In AC/DC converters, they are used to reduce circuit noise, thus preserving signal integrity and improving circuit efficiency. Moreover, it can be also used for interference suppression and line conditioning.

Working Principle

The BFC233864473 film capacitor is based on a polypropylene dielectric film, which is insulated from two external conductors. When a bias voltage is applied, the dielectric film becomes an insulating layer between the two conductors. In this state, the dielectric film acts as capacitance, meaning it stores potential energy. This stored energy is discharged when the bias voltage is switched off.

The BFC233864473 film capacitors are constructed with respect to environmental requirements such as low moisture absorption, low outgassing, and reliable long-term performance. As such, they are designed to withstand extreme conditions, such as vibration, shock, high temperature, and humidity.
