Film Capacitors

A film capacitor is an electrical component — a capacitor — constructed in a layered structure of thin plastic film. Film capacitors differ from conventional capacitors mainly in their small size and high capacitance at a low voltage rating, making them ideal for use in many electronic circuits. Film capacitors are defined by their construction method, in which thin, alternating layers of polymer film are used to create multiple capacitors between two conductive plates. The MKP385268125JD02W0 is an example of such a type of capacitor.

Application Field

Given their size, physical robustness and temperature stability, film capacitors are ideal for a variety of uses. Among their most common uses, film capacitors are often found in audio power amplifiers, voltage compensators, mains filters, and switch-mode power supplies. They are also often used in frequency filters, as they can filter out any frequencies below and above certain frequencies. Furthermore, they can be used as hold-up capacitors for short-term storage of power and to reduce transients in power supplies.

Working Principle

The MKP385268125JD02W0 film capacitor is a low voltage, high capacitance device known as a metallized plastic film capacitor. It consists of a metal-impregnated dielectric medium, encased in a non-conductive material and hermetically sealed for insulation. The working principle is based on the dielectric properties of the material, which is able to store and release electrical charge by increasing and decreasing the voltage applied to it. The device works via the accumulation of electrical charges on the metal plates, allowing it to act as an electrical energy storage medium capable of holding large amounts of charge at any given time.

The film capacitor is a highly efficient and reliable component often used in modern electronic designs. Due to its high capacitance values, it is able to effectively store a large amount of energy and can also provide a significant buffer between the power supply load and a DC reference. It is this buffer effect that makes film capacitors preferred in many low-phase- noise and low-ripple designs.
