Film Capacitors

A film capacitor, also known as a plastic film capacitor, polyester capacitor, or dielectric film capacitor, is an electrical capacitor that utilizes a thin plastic film as the dielectric. These capacitors contain two electrodes, called “electrodes”, that are separated by an insulating dielectric medium. The dielectric may be plastic, paper, ceramic, glass, or a variety of metals, such as aluminum, stainless steel, and copper. The electrodes are typically metal plates or films, such as copper, tin, silver, and aluminum.

Film capacitors are often used in applications such as signal filtering, voltage regulation, energy storage, power conversion, and power distribution. They are also used in the filtering and coupling of radio frequencies. The primary advantage of film capacitors is their low leakage current, high stable capacitance, high ripple current, and wide frequency range. 

The MKP385662016JYI5T0 film capacitor is a general purpose radial-leaded film capacitor with an operating temperature range of -40°C to +85°C. This capacitor has a useful life of 1000 hours at a maximum operating temperature of 85°C. It is rated for a nominal voltage of 250V and has a capacitance value of 1μF, with a maximum allowable ripple current of 450mA. Due to its small size, the MKP385662016JYI5T0 can be used in a wide variety of applications.

The working principle of a film capacitor is based on the electrochemical phenomenon. When a voltage is applied to the capacitor, charge is stored on the capacitor electrodes. The rate of storage is proportional to the applied voltage, the distance between the electrodes, and the dielectric of the capacitor. The capacitor stores the charge until the time that it is discharged.

The MKP385662016JYI5T0 can be used in a variety of applications including decoupling, smoothing, snubber circuits, and protection circuits. Decoupling is a technique that is used to prevent noise interference and create a low-noise electric and power distribution network. By using film capacitors, this decoupling effect is enhanced. Smoothing is the use of a film capacitor to reduce transient voltage spikes and reduce the ripple voltage. Snubber circuits are used to protect sensitive components from voltage spikes that may occur due to switching. Protection circuits are also used to protect sensitive components from high voltage or current spikes.

Film capacitors such as the MKP385662016JYI5T0 can be used in a variety of applications and are known for their low leakage current, high stable capacitance, high ripple current, and wide frequency range. The working principle of this type of capacitor is based on the electrochemical phenomenon, whereby charge is stored on the capacitor electrodes and then discharged upon the application of a voltage. This capacitor can be used in applications such as decoupling, smoothing, snubber circuits, and protection circuits.
