Film Capacitors

Film capacitors, also known as plastic film capacitors, are capacitors made with film as the dielectric material. These capacitors are usually characterized by their good performance in high-frequency applications, good temperature and voltage properties, and high insulation resistance. They are becoming increasingly popular due to their very low self-inductance and wide frequency range, as well as their low parasitic parameters. In general, the film capacitors have an operating temperature range of -55°C to 150°C.

The QXP2E335KRPT film capacitor is a high-end product providing excellent screening performance, good internal consistency and long-term reliability in high-frequency and power applications. It features low ESR, high frequency, low dielectric absorption, and high insulation resistance. Furthermore, the QXP2E335KRPT film capacitor has wide operating temperature range from -55°C to +125°C and can withstand up to 2400 Volts AC.

Working Principle

Film capacitors work on the principle of storing electrical energy in an electric field between two conductors separated by an insulating film. When an alternating electrical current is applied to the two plates (the two conductors), the electric field between them is periodically reversed, thereby storing and releasing energy in the form of electrical or magnetic fields. This principle is the same regardless of the film material.

The QXP2E335KRPT film capacitor utilizes a polypropylene film as its dielectric material. It is denser than other materials, such as paper or plastic, which allows it to retain a higher charge and maintain its form even under harshest conditions. Furthermore, the polypropylene used in the QXP2E335KRPT film capacitor provides excellent levels of humidity resistance and makes the capacitor ideal for a variety of harsh environment applications.

Application Field

The QXP2E335KRPT film capacitor has a wide range of applications due to its many features such as low ESR, high frequency and high insulation resistance. It is primarily used in power devices, high-frequency switch-mode power supplies, motor drivers, wireless technology and instrumentation circuits. It is also used in outdoor-rated motor drivers, power channels, and mobile applications due to its high temperature and voltage properties and reliable insulation.

In addition, the QXP2E335KRPT film capacitor is used in resonant converters due to its low dielectric absorption, allowing for more efficient energy management. The capacitor is also ideal for high-power automotive applications, as well as low-noise audiophile audio equipment. Finally, the capacitor can also be used in audio circuits and high-stability timing applications due to its wide frequency range and low self-inductance.
