Film Capacitors

Film capacitors are a type of capacitor that utilizes a film as the dielectric material instead of the traditional ceramic or paper dielectric. Film capacitors are composed of two electrodes separated by a dielectric material. The dielectric film is usually made of polycarbonate, a derivative of of polyethylene terephthalate (PET), or a mixture of polyethylene terephthalate and polycarbonate. The electrodes terminal electrodes are usually metal and are soldered or welded to the capacitor\'s terminals.The ECQ-V1H124JLW is a standard medium-voltage film capacitor which is used for applications requiring high-quality signal filtration. It possesses a wide operating temperature range from -55˚C to +105˚C and has a very low dielectric absorbing property. Its small physical size and weight makes it ideal for parameters that require compact and light solutions.

Working Principle

Film capacitors work in a similar manner as other capacitors, allowing an electric charge to be stored and then released at the same rate. The opposite side of the dielectric film is typically coated with a thin metal film which serves as the other electrode. When the capacitor is charged, the current flows through the metal film and causes a separation of charge on each side of the dielectric film. This forms an electric field which creates an opposing voltage across the capacitor.When the capacitor is discharged, the current flows back through the metal film and the electric charge is removed. The size and distance between the two electrodes, along with the properties of the dielectric film, determine the amount of capacitance (the ability to store an electric charge).

Application Field

Film capacitors are mainly used in power supplies, audio and video equipment, power quality control, and high-powered industrial drives. ECQ-V1H124JLW capacitors are usually found integrated into power supplies used in lighting, medical equipment, motion control, motor drives, and automotive applications.Having a wide temperature range, these capacitors have excellent surge capabilities, making them ideal for applications that require high-speed operation. They also have good load life characteristics, meaning that they are able to maintain their capacity after many applications of high-voltage.

Conclusion

Film capacitors, such as the ECQ-V1H124JLW, offer both power and signal filtration solutions and have applications in many industries. These capacitors boast excellent surge capabilities, excellent load life characteristics, and a wide temperature range for stable performance. Film capacitors are a cost-effective and reliable way to achieve improved power control and long-term reliability.
