Film Capacitors

Film capacitors, also known as plastic film capacitors, refer to capacitors that use plastic film, paper or polyimide film as electrodes. This kind of capacitor has the advantages of wide capacitance range, small size, light weight and good frequency characteristics. According to application field, it mainly includes MKP385416125JIM2T0 film capacitors, metallized film capacitors, dc blocking film capacitors and so on.

MKP385416125JIM2T0 Film Capacitors

As a growing type of film capacitor, the MKP385416125JIM2T0 capacitors are used in many fields, such as telecommunication industry, power electronic systems, automatic control systems, medical, military and avionics systems. The advantages of them are low loss, medium endurance, good stability, wide capacitance range and various types.

Working Principle

Basically, the operating principle of MKP385416125JIM2T0 film capacitors is the same as all other capacitors. It is based on the ability of the capacitor to store electric energy in an electric field when two conductive plates separated by an insulator are subjected to an electrical potential difference. When the AC voltage reaches the electric field between the two metal plates, electric charges of opposite polarity are accumulated, resulting in the formation of an electrical field. This makes the structure of the capacitor like a rechargeable energy storage device, storing some of the charge from the AC voltage.

It is quite simple- the electric field created by the potential difference between the two conductive plates accumulates opposite charges on the surface of each plate of the capacitor. This is the basis of operation and it is how a MKP385416125JIM2T0 type of capacitor functions.

Application Fields

As introduced above, the MKP385416125JIM2T0 film capacitors are used in many fields, such as telecommunication industry, power electronic systems, automatic control systems, medical, military and avionics systems, which makes it a versatile type of film capacitor.
