Film Capacitors

Film capacitors are a type of capacitors built around a plastic film dielectric. These devices have a long lifespan and low losses, meaning they are widely used in a variety of applications such as filters, switches, and bypassing. A well-built film capacitor will retain its physical strength and capacitance even when exposed to extreme temperatures, humidity, and mechanical shock. The BFC236952103 is a type of film capacitor.

Application Field

The BFC236952103 is a film capacitor designed for high-frequency filtering, current limiting, and voltage bypassing applications. It is commonly used in automotive audio systems where it is used as a line filter and for controlling the flow of power to the speakers from the amplifier. It is also highly-effective in reducing high-frequency noise from electronic circuits, and can be used in power design applications to prevent against system failure due to overvoltage or overcurrent conditions.

Working Principle

A film capacitor, such as the BFC236952103, is built around a plastic film dielectric. It stores electrical energy in the form of a static charge between two conductive metal plates. The voltage across these metal plates is limited by the plastic film barrier, and can therefore sustain higher voltage levels than standard ceramic capacitors. Additionally, film capacitors don’t suffer from dielectric absorption and can sustain their capacitance even when exposed to extreme operating temperatures and humidity levels.

The BFC236952103 is specifically designed to prevent higher frequency signals from reaching the circuit, while allowing lower frequencies to remain unaffected. This is useful in automotive audio systems as it helps to reduce motor noise from the vehicles alternator and other high frequency electromagnetic interference from nearby objects. In addition, its low series inductance is ideal for low impedance bypass applications.
