Film capacitors, also known as plastic film capacitors, have been available since the 1930s. Because of their small size, they are often used for electronic applications in which circuit board space must be conserved. Film capacitors are also beneficial in situations where high voltage and high temperature tolerance is required, such as power supplies, motor control, and sound systems. While film capacitors are not typically the best choice for applications where large amounts of capacitance are needed, they can still find a place among the most demanding of applications.

The BFC237175393 is a film capacitor with a particularly favorable combination of features. It has a capacitance of 40μF, rated at 6.3 and 10 VAC. It is group-style with a small size and low profile. The BFC237175393 is a self-healing device, which makes it extremely reliable in the field. Additionally, it boasts high temperature and humidity tolerance and features excellent protection against ESD, humidity, and temperature changes.

The operating principle of film capacitors is based on the behavior of metallized plastic film. As high voltage is applied to the capacitor, an electrical field is created within the polypropylene dielectric layer. This creates a static charge on the film surfaces, which effectively separates positive and negative ions. As the voltage increases, the force of attraction between the positive and negative ions decreases, allowing the capacitor to store more energy.

Film capacitors are excellent for high-voltage, high-temperature applications, where reliability and space requirement are critical. The BFC237175393 is a great example of a film capacitor that can meet these needs. Thanks to its high temperature and humidity tolerance, ESD protection, low profile, and self-healing capability, it can be used in various electronic systems, including power supplies, motor control, and sound systems.
