Film Capacitors

Film capacitors, also known as plastic film capacitors, are capacitors made of plastic. Film capacitors are composed of a variety of plastic film materials such as polypropylene, polystyrene, polyphenylene sulfide, etc., with two layers of aluminum foil electrodes, and the electrodes are melted and pressed with a cold welding process. The dielectric layer of the film capacitor can be adjusted by changing the thickness of the film or the type of plastic. It has high insulation resistance (generally not lower than 103MΩ), excellent high frequency characteristics, low loss, high dielectric strength, large capacity and constant capacitance over a wide temperature range.

B32022B3223M289 application field and working principle

The B32022B3223M289 film capacitor is a low-loss, high-precision capacitor with low AC resistance, which can be used as a DC blocking, pulse filtering and line bypass capacitor in RF front-end circuits and other circuits.

The working principle of B32022B3223M289 film capacitor is actually very simple. The two ends of the film capacitor are the two gray electrodes, that is, two silver lines, connected to two conductors, between the two electrodes, sandwiched by two insulators. When connected to the power supply, the positive and negative charges of the capacitor will flow into the capacitor respectively, and when enough charge enters, the voltage of the capacitor will reach the specified value. Moreover, when the current stops flowing, the capacitor will still store the charges, which can be called the energy storage device.
