Film Capacitors

Film capacitors or plastic film capacitors, is a type of capacitor, typically a wet-cell capacitor, that uses a thin plastic film with a thin layer of metal film deposited on the surface to form the electrical layer of the capacitor. It is a great alternative to ceramic or electrolytic types of capacitor based on the levels of insulation offered to the film capacitor.The ECW-H12562HV is an example of a film capacitor, offering higher insulation and voltage capabilities compared to ceramic capacitors. Its applications include audio equipment, industrial electronics, communications equipment, and automotive electronics.

Working Principle

Film capacitors are generally connected as parallel plates, and when a DC voltage is applied on the capacitor, the electrical field spreads through the film and creates a potential difference between the two plates. The conductive metal film acts as an electrical charge storage device, allowing the electrical field to exist between the two plates even after the DC voltage is removed.The stored electrical charge gradually disperses over the surface of the film during the discharge phase, as the metal film discharges and is conductive, allowing the technology to support a greater amount of voltage, current, and discharge time than other types of capacitor such as ceramic and electrolytic.

Industry Applications

Due to its higher insulation and voltage capabilities, the ECW-H12562HV film capacitor is suitable for a host of applications, particularly those that require a stable operating voltage. In industrial electronics, the capacitor is used to assist in controlling motor speed, such as in variable-speed drives. It can also be used to bridge AC voltage sources, meaning it can be used to power the electrical systems of motion control systems and in industrial automation equipment.The ECW-H12562HVis often utilised in communications equipment such 26GHz base station, RF identification systems and various other device that requires a high-level of protection from EMI (electromagnetic interference). Audio equipment relying on music amplitude modulation may also incorporate the EMH film capacitor, due to its stable performance over time.Additionally, automotive electronics such as Electronic Engine Control (EEC) and cruise control systems also make use of this technology. It is able to protect the circuitry from surge, transients, and other electrical problems that can cause the system to fail.

Conclusion

The ECW-H12562HV film capacitor provides a viable and inexpensive option for certain applications, namely those that require a higher level of insulation than ceramic or electrolytic capacitors can provide. While it is an ideal option for industrial, automotive, communications, and audio applications, it is important that one understands the technological limitations of the ECW-H12562HV film capacitor prior to using it in any given system.
