Film Capacitors

Film capacitors, also known as plastic film capacitors, refer to electrical components manufactured and made by layering multiple layers of plastic film made from materials such as polyester, polyethylene, polypropylene, polystyrene, and Mylar. This type of capacitor usually has a high capacitance, low leakage current, good insulation performance, and can run at high frequency. They are lightweight, compact in size, and offer a wide range of capacitance values, from picofarads to hundreds of microfarads.

Application field

KP1830147014G film capacitors are often used in energy saving lamps to store energy and are also widely used in switching power supplies, power electronic ballasts, display modules, communication equipment, and electrical automotive systems.

Working principle

The working principle of a film capacitor is based on the same principle as any other type of capacitor: by storing electrical energy in an electric field, and then releasing it when necessary. The electrical energy is stored between two metal layers (which form the electrodes) that are separated by a dielectric, in this case a plastic film. When a capacitor is connected in a circuit, the two plates become oppositely charged and an electric field is created. As the current flows in the circuit, the capacitor absorbs electrical energy, which causes the voltage difference between the two plates to increase. When the current stops, the capacitor releases its stored energy back into the circuit, depending on the type of capacitor, the amount of current, and the voltage that it is capable of storing or releasing.

Conclusion

KP1830147014G film capacitors are capable of providing reliable operation in a wide range of applications. They are lightweight, small in size, and offer a wide range of capacitance values, making them suitable for use in many electrical and electronic systems. They are also able to store and release electrical energy efficiently, making them a great choice for applications where energy savings are desired.
