The BFC233621105 is a high-performance, metalized polyester film capacitor. It has a 100V rated operating voltage and a capacitance tolerance of ±20%, making it suitable for use in high-frequency, high-voltage, circuit applications that require precise control of capacitance. Examples of applications where the BFC233621105 film capacitor can be used include DC-DC converters, auxiliary power supplies, and motor controller circuits. It is also suitable for use in other electronic systems, including alternating current with high-bandwidth and high-power applications.

Working Principle

A film capacitor, also known as a plastic film capacitor or a film dielectric capacitor, consists of a film of plastic dielectric material between two metal electrodes. When a voltage potential is applied across the electrodes, an electric field is created in the dielectric material. This electric field causes dielectric polarization, which causes the dielectric material to store an electric charge. The amount of charge stored is proportional to the applied potential, and this is the basis of the capacitance of the capacitor.

The dielectric material used in the BFC233621105 is metalized polyester film, which is able to provide greater temperature stability and higher capacitance values than other types of plastic films. The capacitance value for the BFC233621105 film capacitor is 1.0uF. The capacitance value is usually measured at 100V or 250V, depending on the application.

The metalized electrodes are designed to provide good electrical contact with the film, improve its stability, and reduce leakage current. The electrodes also protect the dielectric material against breakdown and ensure maximum power dissipation. The BFC233621105 film capacitor has a rated operating voltage of 100V, which makes it suitable for use in high-voltage circuits.
