Film Capacitors

Introduction

Film capacitors are high-performance, reliable components used in numerous power applications. They are compact in size and are capable of handling higher voltages than conventional capacitors, with high capacitance values. The most commonly used film capacitors sheet are polyethylene naphthalate (PEN), polyester (PET), polypropylene (PP) and polycarbonate (PC). The advantages of film capacitors include excellent high frequency performances, high insulation resistance, which leads to a larger energy storage capacity and long lifetime.

Applications & Working Principle

BQ014E0562J is a polyester film capacitor and it is applicable to AC voltage control, such as motor control, lighting regulator, inverter, etc. It can be used to provide the necessary insulation and reactances as an energy storage device, and is suitable for general control and power applications.

The operation of a film capacitor is governed by the same principles as those of any other capacitors. The internal structure consists of two parallel conductors that are separated by an insulating medium (or dielectric). The charge is stored on the conductors when they are exposed to an alternating electric field. When a voltage is applied to the capacitor, it will generate an electric field, and a current will flow between the electrodes, resulting in power being stored. Since the dielectric is an insulator, the stored charge will remain the same until the voltage is removed.

The film capacitor has highly stabilized characteristics over a wide range of temperature, voltage, and frequency. Its design permits a low-loss operation, excellent linearity with no dielectric absorption, and good phase-shift characteristics over a wide range of frequencies. This makes BQ014E0562J an ideal choice for prolonging the active lifetime of energized components.

Conclusion

As an electronic component, BQ014E0562J is a high-performance film capacitor used in many applications due to its excellent high frequency performances, high insulation resistance, and a large energy storage capacity. Its wide range of capabilities make it the ideal choice for a variety of power applications, from AC voltage control to motor control and lighting regulator.

The film capacitor is versatile because it operates according to classical capacitor principles, where a charge is stored on two parallel conductors exposed to an electric field. This allows it to generate current, store power, and offer long life and phase-shift characteristics. Ultimately, BQ014E0562J is an optimal solution for engineers seeking longer product lifetimes while ensuring optimal electrical performance.
