Film Capacitors

A film capacitor, sometimes referred to as a foil capacitor, is a type of capacitor that uses a thin strip of plastic film as the insulation between a pair of conductive plates. It is a type of electrolytic capacitor with a low dielectric loss factor and is widely used in many electronic circuits. Film capacitors are partitioned into two categories, depending on their dielectric structure: paper and polyester. Paper capacitors are made of thin strips of paper or cellulose that are impregnated with an electrolyte. Polyester capacitors are formed from thin layers of polyester and copper foil, which are often insulated with polystyrene.

B32562H1475K189 application fields and working principle

The B32562H1475K189 film capacitor is a metallized polypropylene film capacitor used in various AC applications. It is a non-polarized capacitor, meaning it does not have any polarity as its dielectric is made of polypropylene film. Due to its non-polarized nature, it can be used in both AC and DC circuits, and is ideal for AC circuits with frequencies of up to several hundred kHz. The B32562H1475K189 film capacitor features a high dielectric strength and low leakage current, making it ideal for applications like motor drives, switch-mode power supplies, home appliances, electricity power supplies and audio equipment.

The working principle of a film capacitor is based on the principle of electrostatic capacitance. This principle states that when two conducting surfaces are separated by an insulating layer, an electric field is created between them and stored energy is formed. The stored energy in the film capacitor is proportional to the capacitance of the capacitor. The capacitance of the capacitor is determined by the area of the conducting plates, the thickness of the insulator, and the dielectric constant of the insulating layer. In a B32562H1475K189 capacitor, the insulating layer is a polypropylene film which has a high dielectric constant and a low dielectric loss factor, giving the capacitor a high degree of efficiency.
