MKP386M447250JT8

Film capacitors are a kind of polarized capacitor with a linear dielectric which keeps a uniform electrical field during operation. They are used in SMPS, AC Motor Drives, Power Factor Corrections, Audio, Video, Lighting, DC-DC Converters,RF Interference Suppression, DC relays, and more, for applications such as impedance matching, charging, energy storage, filtering, etc. The MKP386M447250JT8 is a popular film capacitor used in a variety of applications.

Working Principle

Film capacitors are polarized devices formed with two electrodes between two metal layers, which act as electrodes and conductors. A dielectric material is placed between the electrodes. The dielectric provides insulation, meaning that it does not allow electricity to flow between the two electrodes. When a voltage is applied to the capacitor, electric field lines form within the dielectric material, causing an electrical charge to build up between the two electrodes. This electrical charge allows for a current to flow through the capacitor when connected to a circuit.

Typically, film capacitors come in three main types: Metallized Film Capacitors, Aluminum Electrolytic Capacitors, and Plastic Film Capacitors. The MKP386M447250JT8 is most commonly a Metallized Film Capacitor. Metallized Film Capacitors feature an etched aluminum foil electroded with metal particles and are characterized by excellent capacitance stability in high temperature environment even under a ripple current and low losses.
