Working principle of BFC247990201

The BFC247990201 film capacitor has a dielectric film between two thin metal electrodes. The unevenness and pores of the surface of the film cause a variation in the gap between the electrodes, resulting in a change in capacitance. When AC is applied, the electrodes of the film capacitor are coupled, and the capacitance between the electrodes is determined by the thickness of the dielectric film and the spacing between the electrodes. The function of a capacitor is to store energy in the form of electric charge, so that a potential difference is generated between its two electrodes. The resistance of the film capacitor to current is very small, and its self-inductance is almost zero, so it can pass AC current, while DC current is blocked.

The BFC247990201 film capacitor has a high capacity and low leakage. With the increase of frequency, the capacitance of the film capacitor is attenuated, and its performance is improved compared with the ceramic capacitor. Due to its low cost and high reliability, it is widely used in various electronic circuits. Therefore, the BFC247990201 film capacitor is an essential electronic component all over the world.
