Film capacitors are used in a variety of applications for both AC and DC systems and are becoming increasingly popular due to their excellent performance characteristics. The QXK2E224KTP7ZHFL is a self-healing type film capacitor with a voltage range of 0.01-230kV and capacitance range of 0.001-1000uF. This capacitor is designed for high-performance, high-voltage applications and has a very low ESR or equivalent series resistance.

Application Field

The QXK2E224KTP7ZHFL film capacitor is suitable for a variety of applications, including resonant circuits, motor drives, snubber circuits, frequency tuning and high voltage pulse applications to name a few. This type of capacitor is especially suitable for high voltage applications as it can handle large voltage spikes without any damage. In addition, it has an insulation resistance of more than 100 GΩ and is suitable for use in temperatures up to 105°C.

Working Principle

The working principle of a film capacitor is based on the electrical and mechanical properties of the dielectric layer. The film capacitor consists of two metal plates which are separated by a thin film of plastic or ceramic material. This film acts as the dielectric layer and determines the capacitance of the capacitor. When a voltage is applied across the metal plates, an electric field is created which produces a charge on the surface of the dielectric. This charge is equal to the amount of charge supplied by the voltage source. As the distance between the plates is very small, the capacitance is very high.

In the case of the QXK2E224KTP7ZHFL, the capacitor is made with a multi-layered polymer dielectric film composed of polypropylene, nylon, and polyolefin. This type of multi-layered dielectric film has a higher breakdown strength than conventional capacitors, allowing it to safely handle high voltage transients without any damage. The self-healing nature of the QXK2E224KTP7ZHFL means that any minor short circuit will be rectified by the on-board protective circuit and the capacitor will continue to operate normally afterwards.

Overall, the QXK2E224KTP7ZHFL film capacitor is an excellent choice for high-performance, high-voltage applications. With its wide voltage range and high capacitance, it is well suited for a variety of applications. Moreover, its high breakdown strength and self-healing capability makes it a reliable and durable option for use in demanding electrical systems.
