Film capacitors, also known as plastic film capacitors, use dielectric polymer films for insulation and are one of the most commonly used components for signal processing, electrical control, power conditioning and power conversion.

BFC236959822 Application Field and Working Principle

BFC236959822 capacitors are mainly used in communication circuits, signal processing, power supply circuits, and various other electronic equipment circuits for filtering, buffering and bypassing. This model offers high reliability, excellent temperature stability, long lifetime and low leakage current. The capacitance range is from 470pF to 470μF with capacitance tolerance of ±10%.

Working Principle

The main functionality of BFC236959822 capacitors is to store energy in the form of an electric field. The energy stored is proportional to the capacitance. A BFC236959822 film capacitor is constructed in the shape of a coil with two metallic plates between a thin film dielectric. When a voltage is applied to the plates, a system of electric charges is generated on the surface of the film. The charges on one plate attract the charges on the other plate, forming a polarized field, and the strength of this field is proportional to the applied voltage. When the applied voltage is removed, the charge of the capacitor is gradually released until the capacitor is completely discharged.
