Film Capacitors

Film capacitors are electronic components that are created with dielectric films. These capacitors are similar to conventional disc ceramic capacitors in that their properties enable them to store electrical energy and limit current flow. However, film capacitors excel in terms of their ability to withstand higher temperatures and maintain high performance during extreme voltage changes. QXP2E155JRP7FT is an example of such a film capacitor.

Application Fields

Due to their excellent temperature tolerance, film capacitors are capable of enduring a wide range of environmental conditions. They are frequently used in power supplies, snubbers, high voltage and high power applications, and general signal processing for an array of applications. They are also able to be used in high-frequency applications, such as radio frequency and microwave, due to their ability to withstand higher temperatures. QXP2E155JRP7FT, specifically, is built to provide users with superior stability and superior protection in high voltage applications.

Working Principle

Film capacitors function similarly to disc ceramic capacitors. An electric field is created when voltage is applied over the plates contained within the capacitor. This field stores electrical energy in the form of an electrostatic charge between the plates. When the voltage over the capacitor reaches a certain level, called the breakdown voltage, the capacitor will temporarily act as a short circuit ensuring that damage is not done to downstream components.

When used in high voltage applications, such as HV optical chips, these capacitors are used to block DC current from passing through the system. By blocking the DC current, the overall temperature of the system is reduced, thus increasing the power efficiency and longevity of the capacitor. QXP2E155JRP7FT is designed with a high breakdown voltage, allowing it to excel in such applications.

Conclusion

The QXP2E155JRP7FT film capacitor is an incredibly well-designed component that can excel in a wide range of applications. Its superior temperature tolerance and high breakdown voltage make it ideal for use in power supplies, snubbers, and high voltage components. Additionally, its ability to block DC current and dissipate heat makes it well-equipped to handle high-frequency applications.
