Film capacitors are energy-storage components used in various electronic systems to store energy and provide reactive current flows. They are made of a dielectric material, typically a film dielectric, between two conductive surfaces, traditionally metal or carbon film. The 475MKP275KJ is such a film capacitor and is ideal for use in applications involving high current surges, high static bias, and requiring low losses.

475MKP275KJ Application Field 

The 475MKP275KJ Film Capacitor is designed for use as a bypass capacitor in applications such as switching power supplies, broadcast equipment, and as part of induction coils. Its broad operating temperature range of -55°C to +105°C ensures consistent performance over a wide variety of environmental conditions.

Additionally, the capacitor features very low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) values as well as high dV/dt (Voltage Rise Rate) ratings, making it the preferred choice for many applications that require sustained energy storage, or where extremely fast transients and hard switching events are present.

The capacitor is also designed for wide range of switch mode power supplies, polarity inverters, induction coils, and loudspeaker crossovers. It is also suitable for use in direct AC-DC conversion, high-efficiency DC-to-DC switching pre-regulators and low EMI applications.

475MKP275KJ Working Principle 

The 475MKP275KJ Film Capacitor works by storing energy in the form of a charge between two surfaces. Unlike conventional capacitors that store energy in the form of an electric field, the film capacitor stores energy in the form of a thin dielectric material, typically plastic or metal oxide. This material conducts an electric current and acts as the insulator between the two plates, allowing direct charge transfer between the surfaces.

Unlike paper capacitors, film capacitors are able to handle extreme temperatures and high ripple currents, making them ideal for applications such as interference suppression and power factor correction. They are also used in radio equipment to reduce pickup and interference from other sources.

The capacitor\'s design helps improve the capacitor\'s efficiency by reducing internal losses, giving it higher capacitance values than conventional capacitors. Additionally, its temperature-resistant construction and high ripple currents make it ideal for applications that require sustained power storage or high transients, such as those required for induction coils or power supplies.

The 475MKP275KJ Film Capacitor is designed for power electronics, providing high ripple currents and low ESR to meet the demanding requirements of applications such as power supplies, induction coils, and pre-regulators.
