Film Capacitors

Film capacitors, also known as film dielectric capacitors, are speciality capacitors, produced with a plastic film as the dielectric. The metallic film is the most common type, where a thin aluminum or zinc layer is deposited on a film of polyester, polypropylene, Teflon, Mylar or cellulose. The aluminum may be combined with other materials such as copper, sapphire, plastic, molybdenum or glass.

The capacitance of these types of capacitors ranges from around 10-6 farads (1 µF)up to about 5000 µF. They have the advantage of a large capacitance range and excellent linearity. Capacitance values can typically be adjusted between 0.05 to 90 % of their maximum rated value.

BFC246829225 Application Field and Working Principle

The Application Field and Working Principle of a BFC246829225 are best described as those of a film capacitor. Film capacitors are mainly used in power electronic applications due to their low voltage and high curren ratings. The BFC246829225 has film-dielectric capacitors with metallized contacts for printed circuit boards. It is mainly used for storing and transferring electrical energy, filtering and bypassing higher frequency noise, or coupling signal applications over a wide frequency range.

The construction of the BFC246829225 involves two layers of a plastic film, such as polyester or polypropylene, alternate between two electrodes. The metal film provides a dielectric barrier that prevents electric current from running through it. When an electric voltage is applied to the capacitor, a charge builds up on the electrodes. This electric field creates an electric field in the dielectric material, which in turn produces an electrical field. The energy stored in the field is what is known as capacitance.

The BFC246829225 is suitable for resonant circuits, DC-DC converters, power supply for inductive load, and ACL filter circuits. It also has good frequency stability due to its high rate capacitance stability. Other features of this capacitor include moisture resistance, excellent electrical insulation, and high dielectric strength.
