Film Capacitors

A film capacitor, also known as capacitance foil or electrical double layer capacitor, is formed when an insulating film, commonly of polypropylene or polyester, is dielectically coated with metal electrodes parallel to each other. Film capacitor’s structure is compact and enables a high rated voltage, allowing it to be used at relatively high voltages. It also has a much higher stability and reliability than an aluminum electrolytic capacitor and is a widely used component in electronic designs.

MKP385424016JD02W0 Application Field and Working Principle

The MKP385424016JD02W0 Film Capacitor is mainly used in the audio sector for the filtering and insertion of capacitor arrays into the power supply for a wide range of components, including amplifiers, transceivers, and audio-visual equipment. The capacitor works by storing an electrical charge, as well as blocking or bypassing a certain frequency in the circuit. This creates a low-pass filter at the capacitor’s corresponding frequency, which is typically around 4kHz. This particular capacitor model has a capacitance of 2700pF, and a rated voltage of 630V.

The working principle is based on the law of capacitance, where when a voltage is applied across a parallel-film capacitor, charge will be stored on the two electrodes. This charge is stored in the form of two electric fields: one between the electrodes, and the other between the electrodes and the dielectric film. The more voltage that is applied, the stronger these electric fields become. As an example, when a 630V voltage is applied to the MKP385424016JD02W0, the electric fields become strong enough to significantly filter out any signals that are above 4kHz.

The MKP385424016JD02W0 is a reliable and efficient capacitor that can provide a reliable and accurate filtering of audio signals. Its main benefit lies in its low inductance and high insulation resistance, which provide a considerable amount of additional functionality in audio design. Additionally, its temperature coefficient and relatively low-cost make it a great choice for a wide variety of audio applications.
