Film capacitors, also known as plastic film capacitors, are capacitors with a plastic film as the medium for electrical insulation and dielectric fixed in the form of thin plates. Generally, the positive electrodes, negative electrodes and insulating layers are wound together, and then rolled into a roll capacitor. The capacitance characteristic of film capacitors depends on the gel performance of the plastic film, and their performance is superior to most dielectric capacitors. The high temperature coefficient and flame retardancy of the electrodes also make film capacitors a good choice in some harsh environments.

BFC238350473 Application Field and Working Principle

BFC238350473 film capacitors are a kind of film capacitor product of Sihui which has the characteristics of good stability, wide temperature range and low cost. Its products are mainly used in high-frequency power supplies, TVs, electronic flash units and the medical industry. This film capacitor features a patented winding technology that eliminates internal spacing, keeping the capacitor compact but allowing for high-quality capacitance.

The working principle of the BFC238350473 film capacitor is that the insulating material is given an electric charge of an opposite polarity, and the closer the poles, the stronger the electrical force, so as to attract each other and generate capacitance. That is, when an alternating current passes through the capacitor, the current will cause the induced opposite electric charge on the opposite plate, which in turn forms an opposite electric field, and the electric field can absorb and store energy. When the capacitor is connected to a circuit, it can not only control the power of the signal, but also filter the signal. This is the effect of the capacitor.

The stability of the BFC238350473 film capacitor is mainly due to the high insulation strength of the film itself. Its inner layer also uses a special solvent-free technology with high density, ensuring zero shrinkage and high reliability. The temperature coefficient of the film capacitor is relatively low, ranging from -20°C to +125°C, so we can use it in different harsh environment.
