Film Capacitors

Film capacitors are nonpolarized energy storage elements that operate without formation of an electrolyte and come in a variety of sizes and forms—including polyester film, polypropylene film, and others. The most commonly used capacitance media is polyethylene (PE), due to its relatively simple manufacturing process and wide range of electrical properties. The QAK2G684JTP is a film capacitor designed for use in power applications, such as high-voltage motor and transformer applications, and is capable of providing a higher capacitance value replacement for a smaller form factor solution.

Application Field

The QAK2G684JTP is a high-voltage film capacitor, rated for up to 1000V, and is suitable for use in high power motor, transformer, and other related industrial applications. It boasts a capacitance value of 2.2µF, and is offered in a through-hole package with two leads. Due to its small form factor, it is capable of replacing larger capacitors with a similar capacitance value while reducing costly board space. In addition, its non-polarized nature makes it a suitable choice for applications that require DC blocking, AC line-coupling, AC decoupling, and power factor correction.

Working Principle

A film capacitor consists of two conductive layers, separated by an insulating medium such as polyethylene (PE). When a voltage is applied, one layer acts as a positive terminal and the other as a negative terminal. The insulating medium stores charges, and the resulting electric field creates the electrical capacitance of the film capacitor. The capacitance of a film capacitor depends on its size, the thickness of the insulating medium and the distance between the plates. For a given voltage, the greater the capacitance of a film capacitor, the greater the amount of energy it can store.
The QAK2G684JTP is designed for use in high voltage applications and can withstand extreme environmental conditions and remain stable under a wide range of temperatures. Its non-polarized nature makes it suitable for applications where no polarity is present, such as high power motor and transformer applications. Additionally, the QAK2G684JTP’s ability to store more energy than a traditional capacitor of similar size allows for a more compact solution with the same performance.
In conclusion, the QAK2G684JTP is a high-voltage film capacitor that is perfect for a wide range of industrial applications, such as high power motor, transformer, and other industrial applications. Its high capacitance value and small form factor makes it an efficient and cost-effective replacement for larger capacitors. Additionally, its non-polarized nature makes it well-suited for applications where no polarity is present.
