Film Capacitors

MKP385413250JPM4T0 application field and working principle

Film capacitors, also named as Polyester capacitors, Polyethylene terephthalate (PET) capacitors, Polypropylene capacitors, and Metallized film capacitors, are one of the most widely used capacitors in the world. The capacitance value of a film capacitor is determined by the thickness, dielectric constant, and area of the film. Generally, the film capacitor is more difficult to miniaturize than other capacitors, and it has excellent characteristics with a wide range of temperature.

Working Principle of MKP385413250JPM4T0

A film capacitor works on the same principle as any other type of capacitor; that is, it stores electrical charge and releases it when a voltage drop is observed across its terminals. The MKP385413250JPM4T0 film capacitor is a non-polarized component, meaning that it does not require an external circuit or a polarized connection.The film capacitor consists of two electrodes or plates, which are separated by an insulating material known as the dielectric. The capacitor works by allowing electrons to accumulate on the plates, forming a static electric field between them. When an alternating voltage is applied to the terminals of the capacitor, each plate will alternate its charge between a positive and a negative polarity at the same frequency as the applied voltage. The electric field between the two plates provides an impedance to the flow of AC current, and the capacitance of the device is determined by the amount of charge stored either side of the dielectric.The MKP385413250JPM4T0 film capacitor offers advantages like lower losses, smaller form factor, higher capacitance, higher insulation resistance, and high frequency behavior when compared to other types of capacitors. Due to its high insulation resistance, it finds its application in the manufacture of RF equipment like radar systems, CDMA radios, and other high frequency circuits.

Conclusion

The MKP385413250JMP4T0 film capacitor is a highly reliable and widely used component in many electronics applications. It offers features like high stability, high maximum operation voltage, good frequency characteristics, low leakage current, and high insulation resistance. It finds its application in the manufacture of consumer electronics, audio equipment, industrial electronics, and RF equipment. Its working principle is based on the same principle as any other type of capacitor; that is, it stores electrical charge and releases it when a voltage drop is observed across its terminals.
