Film Capacitors

Film capacitors are non-electrolytic surface mountable capacitors that are usually made up of plastics, such as polyester, polycarbonate and Mylar. These plastic films can be used singly or stacked together to form a stack of thin film capacitors.

BFC237662682 Application Field and Working Principle

The BFC237662682 film capacitor is a popular and versatile capacitor used in many applications. This type of capacitor is often used as a substitute for electrolytic capacitors, due to their extraordinary stability and their low leakage current. They have the ability to withstand higher temperatures compared to electrolytic capacitors.

In terms of product performance, the BFC237662682 film capacitors are designed to be used at high frequencies and high temperatures. Their interwinding impedance is low, which makes them ideal for frequency conversion applications. Also, their insulation resistance is good, making them capable of withstanding high volatge conditions. Moreover, these capacitors have low ESR stability, allowing them to remain stable under mechanical shock and vibration.

The working principle of BFC237662682 film capacitors is based on the dielectric properties of plastic films. The internal construction comprises of two ultra-thin plastic layers, which are separated by a thin dielectric layer made from Aluminum Oxide. As current passes through the capacitor, it creates an electric field, which causes the dielectric layer to become polarized. This polarization reduces the resistance of the dielectric film and increases its electrical permittivity, thus storing energy.

The most important feature of BFC237662682 film capacitors is that they offer extremely high temperature stability. This is mainly due to their low dissipation factor. The dissipation factor is the ratio of energy lost due to resistance losses to the total energy stored per cycle of operation. The lower this value, the better the temperature stability of the capacitor.

In addition, BFC237662682 film capacitors also offer excellent self-healing properties. This means that they are able to repair any damage caused by electrical stress or breakdown. This feature makes them ideal for use in high voltage applications, as it eliminates the need for frequent replacement of components.

In summary, the BFC237662682 film capacitors have a variety of uses. They are highly reliable and offer great temperature stability and self-healing properties. As such, they are widely used in energy conversion, automotive and industrial applications.
