Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor that uses thin plastic films as the dielectric material. They offer a number of advantages over other capacitors, including higher capacitance values, better temperature stability, and longer life expectancy. The QAP2J105JRP is a film capacitor designed for use in a wide range of applications. In this article, we\'ll discuss the QAP2J105JRP\'s application field and working principle.

Application field

The QAP2J105JRP is a non-polarized film capacitor that provides capacitance values up to 3.2µF. It is used in a variety of applications, including power supplies, motor control, telecom, deflection coils, and audio/video equipment. Because of its non-polarized design, it can also be used in circuits with both AC and DC current.

Working Principle

The QAP2J105JRP is designed with a stem construction that consists of four layers of PET film. The first and third layers have spiral electrodes, and the second and fourth layers have a metallized film. When the capacitance is applied, an electric field is formed between the electrodes, creating a dielectric barrier. This barrier prevents current from flowing between the electrodes, thus forming a capacitor.When being used in a circuit, the QAP2J105JRP acts as an electrolytic capacitor, storing energy and releasing it as needed. It also acts as a filter, reducing noise and providing a more stable power supply. Additionally, the film capacitor\'s construction allows it to operate over a wide temperature range and withstand voltage and current surges.

Advantages

Film capacitors offer several unique benefits over traditional aluminum electrolytic and ceramic capacitors. For starters, film capacitors have a high dielectric strength, allowing them to handle higher voltages with greater reliability. They also tend to have lower leakage current and, as previously mentioned, are non-polarized, meaning they can handle both AC and DC current.In addition, film capacitors have a much longer life expectancy than traditional capacitors, offering up to 2000 hours of operating time without any sign of degradation. This makes them ideal for applications where reliability is important. Finally, film capacitors are more resistant to temperature changes than traditional capacitors, making them an excellent choice for high-temperature applications.

Conclusion

The QAP2J105JRP is a non-polarized film capacitor that offers high capacitance and excellent stability over a wide voltage and temperature range. It\'s well-suited for applications such as power supplies, motor control, telecom, deflection coils, and audio/video equipment. Because of its low leakage current, high dielectric strength, and long operating life, it\'s an excellent choice for applications that require reliability and performance.
