Working Principle of Film Capacitor BFC236868393

Capacitors consist of two conductive plates separated by a dielectric material. When a DC voltage is applied across them, the electric field will form across the dielectric. The applied voltage will attract the positive or negative charges, which will then accumulate on the plates. This process creates an electric field in the dielectric, which will strengthen the source voltage and produce a voltage drop across the plates.

The professional film capacitors BFC236868393 adopt high-quality metallized polyester film as the dielectric, which has the characteristics of high insulation resistance, low dielectric loss, and high working voltage. The metal film is electroplated on the surface with a layer of metal oxide. After the metal oxide layer is insulated from the ground, an effective single-layer capacitance is formed, which can be used to effectively reduce the noise and interference of the computer power supply.

In addition, the film capacitor BFC236868393 has a wide temperature range and can be used in temperature range of –40℃~+105℃. The vibration resistance of film capacitor products can reach 10-20G (according to different products). The special contour design of the film capacitor —- its structure has rounded corners that reduce the risk of electric shock and reduce noise. Due to its good electrical properties, film capacitors are widely used in various electronic devices.
