Film Capacitors: F339MX221031MCI2B0 Application Field and Working Principle

Film capacitors are a type of capacitor which consists of two conductive plates insulated by a film made of polyethylene, polypropylene, or other special plastic material. The F339MX221031MCI2B0 is a film capacitor which has a temperature coefficient of 0.65% per °C and a dissipation factor of 4%. It is widely used in motor control, motor drives, automotive electronics, power electronics, frequency converters, AC adapters, inverters, LED lighting, and power supplies.

The working principle of a film capacitor revolves around the principle of dielectric capacitor. Inside a film capacitor, the dielectric film is the main element, separating the two conducting plates from one another. When a potential difference is applied across the plates, the film behaves like an insulator and does not allow the current to flow through it. However, the electric field created by the potential difference causes the electrons to move from one plate to another, resulting in electric charge accumulation on the capacitor\'s plates. The accumulated electric charge stores electrical energy.

Depending on the thickness and dielectric constant of the dielectric material, a film capacitor can be classified as an X2 capacitor (dielectric constant of 2 or more), an MICA capacitor (dielectric constant of 60 or more), or a PPS/polyester capacitor (dielectric constant of 200 or more). The F339MX221031MCI2B0 capacitor belongs to the X2 type.

The F339MX221031MCI2B0 is a high-value capacitor which can deliver a capacitance range from 1000pF to 3300pF. The capacitor provides excellent stability over temperature and voltage and features low losses of 0.3dB at 10kHz and voltage ratings of up to 275V. It is also resistant to high humidity and can withstand temperatures from -40°C to +100°C. The capacitor design is extremely compact and provides a large capacitance in a small package, making it ideal for use in a variety of applications.
