Film Capacitors

A film capacitor, also known as a paper or an oil capacitor, is a type of capacitor characterized by its decreased size, high stability and insulation, and low losses due to their superior dielectric strength and temperature coefficient compared to other types of capacitors. This type of capacitor can have an applied rating of 10nF to 100mF and can be found in various shapes, sizes, and temperatures.

BFC236727124 capacitors are two-layer aluminium foil metallized polyester film capacitors, equipped with radial lead wires and manufactured in a molded case with snap-in terminals. These devices are internally non-polarized and have a temperature range of -55°C to +85°C.

Application Field

BFC236727124 capacitors are designed to be used in a variety of applications such as decoupling, interference suppression, and power supply filter. The Snap-in mounting feature makes it an exceptionally versatile capacitor for a variety of circuit designs. These capacitors are also used in a wide range of audio and video applications such as in DVD players, satellites, TVs, speakers and audio amplifiers.

Working Principle

Film capacitors are composed of two layers of thin Ag-MnO2 metallized films, making the device self-healing, since in case of overload the film will break before the capacitor’s voltage rating will be exceeded. This self-healing property also helps reduce the chances of explosion or fire damage to the capacitor.

These capacitors are capable of blocking DC voltage, and they can also be used to store energy by storing electric motion and discharging it as needed. The voltage rating of the capacitor is based on the thickness of the film used. The thicker the film, the higher the voltage it can tolerate.

Film capacitors are a great choice for DC filtering applications because it offers good tolerances, superior dielectric strength, excellent temperature coefficient, low leakage current, and long lifetime. Other applications include smoothing ripple in noise circuits, signal coupling and decoupling, and high frequency bypassing. Film capacitors also offer low losses in high frequency circuits and low resonance frequency in low frequency circuits.
