Working Principle

A film capacitor is made up of multiple layers of thin plastic or metalized film which are separated by a thin layer of dielectric material. This insulation material prevents the thin metallic layers from directly touching each other and creates a capacitance between them. Since the metalized film layers are thin, these capacitors are very low in inductance, making them ideal for use in high frequency, high speed AC signals. When a DC voltage is applied to the capacitor, the charge will accumulate in the dielectric material between the two metalized film layers, creating a capacitance.

When an AC signal is applied to the capacitor, the electric field within the dielectric material is constantly changing, which causes a current to flow in and out of the capacitor. This current flow creates an opposing voltage to that of the applied voltage, which creates the filtering and blocking capabilities of the film capacitor.

The BFC2373FF334MD is a great choice for any application requiring a reliable and versatile film capacitor. Its good temperature stability and low dissipation factor make it well suited for high temperature and low frequency signal applications. Its high dielectric strength makes it suitable for high frequency AC signals as well.
