Film Capacitors

Film capacitors, also known as polymer film capacitors or plastic film capacitors, are polarized capacitors with a mass-produced dielectric film made of a thin laminated film of plastic. Film capacitors represent a new generation of capacitors which are smaller in size, more reliable, and have a higher energy density and high frequency performance, compared to traditional aluminum electrolytic capacitors. Among the dielectric films used for film capacitors, plastic film has gained wide use due to its low cost, low losses, excellent dielectric constant, excellent insulation characteristics, good stability, and temperature compensation. Film capacitors have been used in many fields, in particular, in power electronics and electric cars, due to their outstanding properties.

BFC233868395 Application Field and Working Principle

BFC233868395 is a type of film capacitor which is highly reliable and cost-effective. It is mainly designed for pulse applications that require high frequency, high power, and high energy storage capabilities. The capacitor is typically used for damping power supplies and power electronic equipment such as motor drivers, inverters, and UPS, etc. It is suitable for applications requiring high stability, long term life, low voltage distortion, and high shock resistance.

The working principle of this capacitor is based on the charge redistribution mechanism. This capacitor has a folded metallized polypropylene (MKP) dielectric film, which is a combination of metalized foil electrodes and plastic polypropylene film. The MKP electric field extends from the metal electrode and is highly localized within the plastic material. The charge redistribution mechanism is achieved by the electric field created between the electrodes and the dielectric film. This electric field causes a displacement of charge and leads to a difference of potential from one side of the dielectric material to the other, resulting in a built-up of electrical energy. The capacitance of the BFC233868395 is dependent on the thickness of the MKP dielectric film, the area of the electrodes, and the distance between them.

In addition to its outstanding electrical features, the BFC233868395 also offers superior mechanical characteristics. It has superior EMI/RFI shielding capabilities and features a small footprint, which makes it ideal for space-constrained applications. It also features an integrated discharge path, allowing for efficient, accurate, and repeatable discharge of the capacitor and improving safety during operation.
