Film Capacitors

A film capacitor is made from an insulating plastic film with a dielectric layer of metal foil. It typically has two electrodes - one that is made from an electrically conductive material such as aluminum or copper, and one that is made from a film. Film capacitors provide reliable performance in a wide variety of applications, including pulse, control circuits, audio, racing, and power applications. Filmic capacitors have high current rating and excellent dielectric stability.

The 930C1W4K-F series film capacitor is a state-of-the-art film capacitor offering superior performance and reliability. This is a high-power capacitor, designed for use in a wide range of pulse motor control applications including permanent magnet (PM) motors, induction (ID) motors, and switching-mode power supplies. The 930C1W4K-F film capacitor has a wide operating temperature range from -40°C to +105°C, with a wide frequency range and high reliability.

Working Principle

The 930C1W4K-F film capacitor is based on an advanced film dielectric that provides superior performance and reliability. The capacitor is constructed of two electrodes, a metal foil electrode at one end and a plastic film electrode at the other. The dielectric layer between the two electrodes is composed of a special polymer film, which forms a barrier that prevents current flow but allows a voltage to be applied across the capacitor. The dielectric layer also provides an effective dielectric constant, which increases the capacitance of the film capacitor.

When an electric charge is applied across the capacitor, an electric field is created within the dielectric layer. This electric field causes current to flow between the two electrodes in proportion to the applied voltage. This current flow results in a charge on each of the electrodes, and this charge is stored as potential energy in the capacitor. When the voltage across the capacitor is reversed, the electric field in the dielectric layer collapses and the charge is released, resulting in a current flow through the capacitor.

The 930C1W4K-F film capacitor has a high-power rating and is designed for use in a wide range of pulse motor control applications. It is an excellent choice for applications in the automotive, industrial, medical, and aviation industries, where reliable performance is of utmost importance.
