Film Capacitors

Film capacitors come in a wide variety of styles including plastic-film, metalized-film, film-foil, paper-foil, and a dielectric film material combination of paper-polypropylene and polyester-polypropylene. These capacitors are used to store energy in electrical systems for a wide range of applications.

The B81141C1334K000 is a film capacitor specifically designed for advanced power and signal applications. This capacitor is usually used in inverter and UPS systems, DC to AC converters, power supplies, and automotive electronics. It is a temperature-stable, non-polarized Film Capacitor with a high ripple current rating and withstanding high DC voltages.

Working Principle

Film capacitors work on a principle referred to as electrostatic storage. Electrostatic storage is the phenomenon where electrical energy can be stored by the charges on two electrodes separated by dielectric material. The dielectric material between the electrodes causes the charge buildup and creates an electric field that stores energy. As current is applied, electric charges build up and the electric field is increased. When a film capacitor is discharged, the charges on the electrodes are released and the electric field collapses.

Advantages

Film capacitors offer a number of advantages over other types of capacitors such as ceramic, electrolytic and paper-polypropylene capacitors. The dielectric used in film capacitors is incredibly reliable, resulting in a longer lifespan and better performance per application. In addition, film capacitors have high temperature stability, withstanding operating temperatures of -25°C to +85°C and surge temperatures of up to +120°C. They exhibit very low ESR and ESL values resulting in less internal heat dissipation and high efficiency. Film capacitors also realign themselves upon being exposed to AC through the process of ferroelectricity, resulting in low leakage current and noise.

Application Fields

The B81141C1334K000 is used in a variety of application fields such as power electronics, automotive, audio, and industrial control. Specifically, it can be used in inverter and UPS systems, DC to AC converters, power supplies, high-voltage lighting, switchmode power supplies, charge pumps, power factor correction circuits and other installations requiring a long-term stable capacitor with low dielectric absorption.

Due to its high voltage rating, high ripple current capability, high temperature stability, and long lifespan the B81141C1334K000 is an ideal choice for a range of applications from automotive electronics to portable audio applications.
