Film Capacitors

A film capacitor (or plastic film capacitor) is a capacitor used in electronics that is constructed with film as the dielectric. This type of capacitor may also be referred to as a polystyrene capacitor, styrene capacitor, or PME capacitor. Film capacitors are manufactured with a number of dielectrics, including polystyrene, polycarbonates, polypropylene, polyphenylene sulphide, polyester, and various other materials.

BFC238052123 capacitors are commonly used in applications where low failure rates, steady performance with temperature changes, and low dissipation factors are essential. This is why they are often used in automotive, communication, medical, audio, warning, and industrial applications. These capacitors are also known for their long life expectancy, making them popular in areas where long-term performance is a must.

Working Principle

BFC238052123 capacitors are constructed with two thin layers of plastic separated by a thin dielectric layer. This creates an electric field between the two layers, which generates an energy storage effect. When a voltage is applied to the capacitors, the electric field causes a magnetic force that stores the charge in the dielectric. The increased capacitance of the electric field is measured in Farads, which is noted on the capacitors.

The capacitor will also not discharge until the voltage is withdrawn, which makes them ideal for use in maintaining stable voltage. This is why they are commonly used in automotive applications where power supplies need to remain steady. This also makes them ideal for applications requiring very high voltage.

BFC238052123 capacitors can also be used in an application to reduce peak currents. This is because they can absorb, store, and release energy quickly, which can help limit the peak current in an electrical system. This is often used in various types of audio equipment to reduce the risks of electrical shock.
