Film Capacitors

Film capacitor is typically a coated film made of polypropylene which is folded into a very small configuration. It is used in all kinds of electronic devices and appliances. It has a very high frequency holding capability and maintains an efficient operation over a broad range of temperatures. Film capacitors have a wide range of applications in consumer applications like smoothing and power-supply decoupling.

MKP385375016JBA2B0 application field and working principle

MKP385375016JBA2B0 is a type of film capacitor manufactured by Walsin. This type of dielectric structure has an alumina coated (dielectric) film as the core material with silver layers replicating a symmetric design of a double-sided PCB with two terminals, one on each side of the dielectric. The capacitor has a voltage rating of 250V and a capacitance of 1μF.

MKP385375016JBA2B0 are used in applications where higher capacitance values are needed. They are commonly used in synchronization circuits, frequency division circuits, and filters, as well as for inductors and LC filters.

The working principle of the MKP385375016JBA2B0 is to store electrical energy as a potential difference (voltage) across two conductors with equal but opposite charges (electrons). When a voltage is applied across the two terminals of the capacitor, electrons are attracted to the negative terminal and repelled from the positive terminal, creating a net charge on the terminals of the capacitor. This charge creates a potential difference between the two terminals which is stored as electrical energy.

The amount of stored energy is determined by the capacitance of the capacitor, which can be changed by increasing or decreasing the thickness of the dielectric materials used in the core. As capacitance increases, so does the amount of stored energy in the capacitor.

The energy stored in the capacitor can only be released when a circuit reaches the same potential difference required to create the charge in the first place. When the circuit reaches equilibrium, the stored energy is released for use in the circuit. This is why capacitors are used to smooth out voltage fluctuations and power-supply decoupling.

Conclusion

The MKP385375016JBA2B0 film capacitor produced by Walsin is a dielectric structure composed of an alumina coated (dielectric) film with silver layers. It has a voltage rating of 250V and a capacitance of 1μF. This type of capacitor is primarily used in synchronization circuits, frequency division circuits, and filters, as well as for inductors and LC filters. It uses the same principle as other capacitors, storing electrical energy as a potential difference between its two terminals.
