Film capacitors, or film dielectric capacitors, are components that are widely used in the electronics industry. The film-dielectric capacitor, such as the BN104K0472K, is a combination of a multilayer dielectric film system and an internal and external metal foil structure. It is made of precise and orderly alternating layers of metal foil electrodes and dielectric films, which are rolled, vacuum-sealed and formed into a cylindrical form. Film capacitors are mainly divided into medium and high voltage types according to their different working voltages.

The BN104K0472K film capacitor belongs to the medium voltage type, and its nominal operating voltage is 630V. It is mainly used in a variety of electrical circuits for AC (Alternating Current) and AC voltage measurement and protection purposes. This capacitor can effectively reduce the current variation along with AC Sinusoidal Current and guarantee the voltage stabilization. It also has the advantages of a good high-frequency characteristic, a large capacity, a wide temperature range and a long service life. It can be used for various types of circuit fields, such as motor control, power factor correction, EMI harmonic suppression, surge protection, IGBT/MOSFET gate driving, etc.

The working principle of a film capacitor can be simply described as follows: when the current charge passes through the capacitor, the electric field of the metal foil layer is generated. The generated electric field induces and stores electrical energy in the film dielectric layer. The accumulated electric energy then injects the current into the circuit, forming a capacitor.The film of BN104K0472K have a 4.72uF capacitance and tolerance of ±3%, according to its specification.

The main advantages of film capacitors are their reliable and stable performance and high capacitance density, which makes them suitable for the design of electrical equipment. The application field of the BN104K0472K film capacitor includes audio systems, IT, medical systems, home appliances, automation control, communication equipment, etc. All in all, BN104K0472K can be seen as an important component in many electronics products.
