Film Capacitors

Film capacitors are capacitor devices that use thin plastic or paper layers as insulating dielectric layers. The ECW-H12752HL is a film capacitor that features a cylindrical stainless steel case with UL Approval that is highly reliable and low profile ideal for use in applications where space conservation is essential. This particular capacitor has a rated voltage of 350VDC and is used in a variety of applications and settings.

ECW-H12752HL Application Field

ECW-H12752HL film capacitors are commonly used in industrial control systems, renewable energy, medical and military applications. They offer excellent pulse handling capabilities and are often used to filter out transients in DC supply circuits, adjustable speed drives, and static converters. Due to the reliability of these capacitors, they are often used in mission-critical applications where continuous operation is required. In addition, film capacitors are often used for RF communications, such as satellite communication systems, direction finding systems, cellular base stations, and tactical communication systems. As they offer superior temperature range and capacitance stability, film capacitors provide reliable coupling/decoupling and RF mask interfacing in these applications.

ECW-H12752HL Working Principle

Film capacitors work by storing electrical charge between two metal plates that are separated by an insulating layer. The type of insulating materials used in film capacitors are typically various types of plastic, paper or ceramic. When a voltage is applied across the capacitor\'s plates an electric field is created, and electrons build up on the plates.When the electric field reaches a particular strength, the ensuing attraction between the two plates of the capacitor causes electrons to flow in the opposite direction, filling the region between the plates with an electric charge. This charge is able to be drawn out of the capacitor by connecting it to a circuit. The amount of charge that can be stored in film capacitors is determined by a combination of the size of the plates and the type and thickness of the dielectric material used. This makes film capacitors useful for many different applications as they can be customized to the particular requirements of each application. During operation, the electric charge stored in the capacitor plates is dissipated slowly through the dielectric material until the capacitor is effectively discharged. This discharge time is known as the dielectric constant, and is usually specified in terms of time.

Advantages of Film Capacitors

Film capacitors offer several advantages over other types of capacitors. They are generally more reliable than other types of capacitors, with better temperature performance and long term aging characteristics. They also offer better capacitance stability and lower parasitic inductance in circuits. This makes them particularly well suited to high frequency applications, where their superior performance is essential. Furthermore, film capacitors are typically lighter and smaller than alternative capacitors. They can also be customized according to needs, with features such as pressure contacts or mounting tabs allowing them to be used in a variety of settings.

Conclusion

The ECW-H12752HL film capacitor is an ideal capacitor for use in industrial control systems, renewable energy, medical and military applications due to its superior pulse handling capability, temperature range, capacitance stability and low parasitic inductance. Furthermore, its small size, light weight, and customizable features make it a great choice for applications where space and weight are important considerations.
