F339X122248MDA2B0 Datasheet/PDFFilm Capacitors
A film capacitor is a type of capacitor that uses thin dielectric films for its principal component. Film capacitors are also known as plastic film capacitors, plastic film dielectric capacitors, film dielectric capacitors, across-the-line type capacitors, and motor-run capacitors. The most common dielectric film used is polyester (also known as Mylar). However, other materials are used, such as polycarbonates, polypropylene, polystyrene, teflon, and others. Film capacitors are constructed with two metal electrodes, known as plates, that are separated by a thin dielectric film. This combination of material helps create a brilliant capacitor, as the metal plates provide a high energy density and the dielectric’s ability to store electrical energy gives it a high capacitance.
F339X122248MDA2B0 Application Field and Working Principle
The F339X122248MDA2B0 is a high quality film capacitor manufactured by Everdiodes. This capacitor is designed for use in various applications, such as high frequency switching power supplies, motor control circuits, and automotive EMC filtering. It also works well as an output filter for LCD backlights. The main features of the F339X122248MDA2B0 film capacitor include its high energy density, low impedance, and excellent thermal stability.
The F339X122248MDA2B0 works by providing an electrical field for storing and controlling the level of energy. When a potential difference is applied to the capacitor from an external source, the metal plates on either side of the dielectric material becomes charged with opposite polarity. This creates an electrostatic field between the metal plates that in turn creates a dielectric field within the dielectric. The dielectric is then able to accumulate electric charge, thus storing energy. When the capacitor is discharged, electrical energy is released and the capacitor is reset ready for the next cycle.
The F339X122248MDA2B0 film capacitor offers excellent performance characteristics in terms of its high energy density, low impedance, and excellent thermal stability. This makes it ideal for many high frequency switching applications and motor control circuits, and its suitability for use in automotive EMC filtering and LCD backlight output filtration makes it perfectly suited for use in a range of modern applications.
