Film capacitors, also known as paper capacitors, plastic film capacitors or dielectric film capacitors, are passive electronic components used to store electrical charge. In general, a film capacitor consists of an envelope, usually made of plastic, metal or paper, which contains a dielectric material and two layers of conductive material, often in the form of aluminum foil or metalized polyester film. The MKP1837368013W is a product belonging to this type of capacitors.

The MKP1837368013W is designed to be used in a wide range of applications such as signal line, high frequency decoupling and bypass, coupling input power, storing energy, noise filtering, and polarity protection on DC switching power supply. It is designed to work reliably in both analog and digital circuits in high frequencies, with a working power range of 125 °C and a voltage range of 50 VDC to 630 VDC.

The main advantage of the MKP1837368013W lies on its operating principle: the self-healing effect. This property is characteristic of film capacitors, and it is important to know in order to understand how this type of capacitor works. In short, the self-healing effect is the result of the electrical breakdown of the film dielectric when it is subjected to a voltage greater than its rated value. When this happens, a small bridge (or fusion) is formed between the two main internal electrodes which dissipates the excessive energy stored in the capacitor, thus protecting the internal components from heat or other damages. As the amount of energy dissipated is much smaller than what was initially stored, the capacitor will continue to work as usual when the voltage stress is removed.

The barrier layer of this capacitor is able to efficiently dissipate the excess energy stored and is capable of long-term operation. It also features a high radius of curvature for its shape, increasing the surface area of contact between the electrodes and the dielectric material, allowing higher rated capacitance values and more efficient energy transfer. Additionally, the MKP1837368013W is designed to have low internal resistance, allowing it to offer low ESR (Equivalent Series Resistance) values and higher ripple current ratings.

In conclusion, the MKP1837368013W is a film capacitor designed for a wide range of applications in signal line, power input, energy storage, and noise filtering. Its wide power range, high frequency operation, and self-healing effect make it a reliable and efficient choice. Furthermore, its high radius of curvature, low internal resistance, and high ripple current ratings make it suitable for a variety of applications.
