Film Capacitors

Film capacitors are a unique class of capacitors well-suited to a variety of applications because of their high stability, high dielectric strength, long life, and small size. The BFC233990056 film capacitor is particularly suited for high stability and long life.

Application Field

The BFC233990056 film capacitor is suitable for applications which require a high degree of performance and stability characteristics, such as high frequency switching, power transmission, power systems, telecommunications, and audio/video applications. It is designed to provide reliable performance in a variety of RF power switching and circuit protection applications. This capacitor is designed to provide operational stability over a wide temperature range from -55°C to +85°C. It can also withstand high voltage, up to 2KV.

Working Principle

The BFC233990056 is a polypropylene film capacitor. This type of capacitor is made from two pieces of plastic film sandwiching a dielectric material. The dielectric material is a dielectric oxide, like aluminum or tantalum pentoxide. This oxide material is neutral in charge and holds an electric charge when a voltage is applied.

When voltage is applied, the oxide material produces a surface charge. The two pieces of plastic act like conductive plates to form an electrostatic field between them. This electrostatic field is capacitance, a measure of a capacitor\'s ability to store and release electrical energy. It is measured in Farads.

The BFC233990056 polypropylene film capacitor has a high dielectric strength and a wide operating temperature range, allowing it to handle higher voltages and remain stable over a wide temperature range. This makes it well suited to high stability RF power switching and circuit protection applications. The long service life and high voltage rating make it a reliable choice for long term applications.
