MKP385482025JFI2B0

Film capacitors are electrical energy storage devices which have very high energy density, making them ideally suited for high power applications. The MKP385482025JFI2B0 is a film capacitor in the range of film capacitors. This is a high voltage, high current, low value capacitor, of the MKP type.

A film capacitor consists of two electrically conductive plates, which are separated by an insulating layer of film. This film can be made of paper, polyethylene, polypropylene, polycaprolactone or polycarbonate. The film is impregnated with a low molecular weight wax, which provides a high dielectric strength when the plates are connected. The size of the capacitor is usually determined by the size of the plates. Film capacitors are usually manufactured in narrow, long strips.

Application Field

The MKP385482025JFI2B0 has a wide range of applications, particularly in DC/DC converters, line drivers and power supplies. The capacitor can be used for applications requiring high value and low ESR, such as solenoid and relay circuits, motor control, PFC, UPS, and SMPS. The capacitor has excellent energy storage properties and is suitable for high power applications with high working frequencies.

Working Principle

Film capacitors work on the principle of electrostatic storage. When a voltage is applied between the plates, electrons are accumulated at one plate, and a charge is created on the other plate. This charge attracts a negative charge from the air in its vicinity, forming an electric field. This field enables electrostatic storage of energy in the capacitor.

At the dielectric level, the electrons become distributed or localized, depending on the applied voltage. When the voltage is removed, the charge on the plates is reversed, and the energy is returned to the circuit. The time required for this energy return is referred to as the electrical time constant.

The MKP385482025JFI2B0 is a high quality film capacitor. The plates are made of aluminum foil and the dielectric is a polymer. The capacitor has a low DC resistance and is highly stable under extreme temperatures and humidity. The long life of the product allows it to be used in a wide range of demanding applications.

The MKP385482025JFI2B0 is a high performance film capacitor that is well suited for high power applications. It has excellent energy storage properties, excellent temperature stability, and a long life. The capacitor can be used in a wide range of applications requiring high value and low ESR.
