Film Capacitors

The BFC237115184 is a polyester film capacitor that is typically used for DC filtering applications. It offers excellent electrical characteristics such as high stability, low losses, and low leakage currents. This type of capacitor is ideal for use in electronic circuits requiring stable DC voltage or power supply for motors, machines, and other equipment.

Application Field

The BFC237115184 is ideal for use in electronic circuits requiring DC voltage or power supply for motors, machines, and other equipment. It can be used for applications such as in air conditioners and office automation equipment, in switched-mode power supplies, AC motor drives, switching regulators, telephone & LAN systems, and bass-reflex type speaker systems.

Working Principle

A film capacitor consists of two metal plates which are separated by an insulating layer. The metal plates are usually made up of aluminum or copper, and the insulating layer is made up of polyester or polypropylene film. When an external voltage is applied across the terminals of the capacitor, a uniform electric field is produced inside the insulation layer. This electric field causes a displacement current to flow in the form of electrons and positively charged ions. As the electric charges accumulate on both sides of the dielectric layer, the capacitor stores electrical energy.

When the voltage is removed, this stored energy is released in the form of a discharge current, which then flows through the circuit. This discharge current is necessary for the capacitor to maintain its capacitance value. The BFC237115184 can withstand extreme conditions, such as high temperatures, high humidity, and heavy shock or vibration. It is also capable of providing long-term operation and can tolerate changes in DC voltages and ripple currents.
