Film Capacitors

BFC237547122 Application Field and Working Principle

Film capacitors are a type of capacitor with an insulation dielectric made of a thin film of plastic. Typically, the dielectric is a polyester, polycarbonate, or polypropylene material, though some film capacitors may use polyethylene naphthalate (PEN) or a hybrid material. The insulation film is often very thin, allowing for the construction of high-capacity capacitors in relatively small footprints. Film capacitors are found in a wide range of applications and sizes, with several different construction types available to meet a variety of needs.BFC237547122 is a type of film capacitor produced by Murata Manufacturing Corporation. This capacitor is designed for d.c. blocking, snubbing, and filtering applications in power electronics systems including switch-mode converters and motor drives. It features a low ESR, a wide temperature range, and a wide range of capacitance values.The BFC237547122 capacitor has a blue plastic package with two leads for connecting to a circuit. The capacitance value of this type of film capacitor is typically marked on the package, with the lead pitch (the distance between the two leads) also indicated. The capacitor will typically be marked with an “F” for one lead and a “C” for the other.At the heart of a film capacitor is its dielectric core. This dielectric is typically a plastic material such as polyester, polycarbonate, or polypropylene. The dielectric material is interspersed with metal layers which form the two electrodes of the capacitor. The capacitance of the device is determined by the area of the electrodes and the thickness of the dielectric layer which separates them.The working principle of the BFC237547122 capacitor is essentially the same as all other types of film capacitors – when voltage is applied across the two electrodes, the dielectric layer between them stores the electrical charge, thus providing the desired blocking, snubbing, or filtering functions. When the voltage across the capacitor is greater than the dielectric’s breakdown voltage, the capacitor begins to conduct and the electrical charge is discharged.In addition to the BFC237547122 capacitor, Murata offers a variety of other film capacitor products. These include radial-leaded plastic packages for power, high-power SMPS, and general-purpose applications, as well as SMD packages designed for high-frequency applications. Murata’s film capacitor products are suitable for use in a wide range of applications and provide excellent performance and reliability at affordable prices.
