Working Principle of the MPX474K305E

The MPX474K305E is a film capacitor that uses a plastic dielectric medium. It is composed of two sheets of conductive material separated by a thin dielectric layer. As electricity passes through the capacitor, a charge builds up on the plates, storing energy in the form of electrical potential. When an external voltage is applied to the capacitor, the charge across the plates is redistributed and the capacitor can discharge or store energy as needed.

The MPX474K305E is designed to provide a high capacitance in a wide temperature range. The capacitance of the device is determined by the thickness of the dielectric layer and the area of the plates. It is also determined by the dielectric constant of the medium and the distance between the plates. The dielectric constant of the medium is affected by the temperature, which means that the capacitance of the device can change depending on the temperature.

The MPX474K305E is a high-performance device that is designed to provide a wide capacitance range in a variety of applications. It is ideal for use in applications such as power factor correction, power conversion, noise suppression, and high-voltage applications. It offers good electrical performance, low leakage, and a wide temperature range.
