Film Capacitors

Film capacitors are used in virtually every electronic device, from home appliances to computers, to aerospace equipment. These capacitors are constructed from polypropylene film or polyester film and come in a variety of forms, including radial leads, axial leads, and snap-in capacitors, that each have their own unique application and working principle.

Of these capacitors, the PVC625 Series is a radial film capacitor developed for use in various applications such as motor control, industrial automation, data processing and communications. It offers a wide range of features conducive to fulfilling the requirements of different types of industrial applications.

Application Field

The PVC625 Series capacitors have the following five different forms: radial miniature, radial, super, high pulse and high temperature radial. All of these capacitors are suitable for use in high performance applications that need an extended voltage range of up to 1600V DC and a high insulation resistance, making them ideal for a variety of applications including industrial motor control, power conditioning, switch-mode power supplies, DC circuit, and other power conversion systems.

The PVC625 Series also offers an additional benefit of a long life span in comparison to other film capacitors which makes it a favorable choice for industrial applications such as PFC, harmonic filter, UPS, motor soft start, and welding machine. This product could also be used in various other industries such as wind turbine, medical equipment, safety protection, and low voltage or servo motor.

Working Principle

The PVC625 Series is a radial film capacitor that uses polypropylene film and metalized electrodes to construct the capacitor. Polypropylene film is known for its good quality of insulation which makes it able to withstand large voltages with minimal leakage current and less distortion. The metalized electrode is then placed on both the polypropylene film and the foil, which is used to collect the electric charge and store the energy. The capacitors are also equipped with non-inductive winding construction, allowing them to have higher impedance values. The combination of these components allows the capacitor to store and release energy in a useful manner.

The PVC625 Series is a high performance capacitor that calculates the total capacitance as the anode is charged and discharged. This capacitor primarily works by creating an electrostatic field between two dielectrics and storing the amount of charge that is equivalent to the capacitance. In most cases, the capacitance of the capacitor can be measured based on the voltage applied. The characteristics of the capacitor can be further adjusted by the addition of additional dielectrics and electrodes, which will influence the amount of charge stored.

During charging and discharging, the energy stored in the capacitor can be released as well. The energy is then released as electrical current, which could be used to power any device. This makes the capacitor ideal for any application where rapid energy delivery is required and the operating voltage needs to be consistent over a long period of time.

Conclusion

The PVC625 Series capacitor is a highly reliable, high pulse, high temperature radial capacitor that is suitable for use in a variety of applications. It offers features such as extended voltage range, high insulation resistance, and long life span. Its working principle is based on the electrostatic fields created between two dielectrics and its charge is measured by the voltage applied. The stored energy in the capacitor can also be released as electrical current when required.
