Film Capacitors

Film capacitors are manufactured from a wide variety of thin plastic films, including polyester, polypropylene, polycarbonate, polyphenylene sulfide, polyethylene naphthalate, and polysulfone. Construction and construction methods vary, but the most common type is the multi-layer constructions.

BFC241918202 Application Field and Working Principle

The BFC241918202 film capacitor is a radial-leaded capacitor with a voltage rating of 380Vdc, a capacitance of 20 µF and a maximum operating temperature of +85°C. It is suitable for use in applications where low voltage and low ESR (Equivalent Series Resistance) are required. The capacitor is built using an epoxy-resin coated Mylar film, which is then wound and sealed in a two-piece aluminum case. The construction of this type of capacitor allows for a very low self-inductance due to the low interwinding spacing and has excellent temperature capabilities.

The working principle of the BFC241918202 film capacitor is based on the idea that layers of dielectric material (such as plastic film) can be used as a charge storage device. This is due to the fact that when the layers are thin enough, they act as a dielectric (non-conductive) material, preventing the flow of charge, and thus storing the charge. As a result, when a voltage is applied, a charge builds up across the layers, and this charge is stored until it is dissipated.

The BFC241918202 film capacitor is capable of handling high surge currents and is able to withstand harsh environmental conditions such as high temperatures and humidity. Additionally, its low profile design makes it suitable for many applications, such as air conditioning, motor control, lighting, and audio applications.
