Specifically, this film capacitor has a capacitance of 0.01μF, working voltage of 400VAC, dimensions of 3.2 x 5.3mm, tolerance of ±10% and temperature coefficient of -55/+155ppm/°C.

The wide working temperature range and excellent high frequency characteristics of this film capacitor make it suitable for a variety of applications. It is often used in high-end home audio products, automotive electronics, computers and other video equipment, security systems, air conditioner industry applications and more. In addition, this series of film capacitors has good moisture resistance, high insulation resistance and good electrical stability.

The working principle of the film capacitor is based on the principle of electrostatic capacitance. Electrostatic capacitance is a type of capacitance that exists between two conducting plates and a dielectric medium between them. When a voltage is applied to the two plates, the electric charges of the two plates are forced to move together and make the capacitor work. The dielectric material is used to isolate the two plates, and then when the voltage is applied between the two plates, electric charges accumulate on the plate and create electric potential.

The electric potential generated between the two plates in a film capacitor will vary depending on the dielectric\'s permittivity and thickness. The dielectric material of the film capacitor acts as a structure that stores electric charges. Therefore, the film capacitor is capable of storing greater electrical energy than conventional electrolytic capacitors.

Overall, the B32529C8103K189 film capacitor is a highly reliable and efficient device that can be used in a variety of applications. The advantages of film capacitors over other types of capacitors include their stability over time and temperature range, good high frequency characteristics, excellent volumetric efficiency, low stray field, and good moisture resistance. This makes the film capacitor an ideal choice for a wide range of applications that require stable, high-frequency performance.
