Film capacitors are electrical components that use thin films as the dielectric material instead of the more commonly used materials such as ceramic and electrolytic. Film capacitors are known for their high stability, high tolerance, low loss, and good temperature characteristics, as well as being less prone to moisture and extreme temperatures. This makes them ideal for applications such as energy storage, voltage filtering, coupling, and decoupling in more demanding environments where reliability is a key factor.

The ECW-H12622JV is a range of film capacitors from Panasonic’s ECW series, designed specifically for use in high frequency power converters. These capacitors use large diameter sleeves to allow for a significant increase in energy storage capability compared to standard film capacitors. The ECW-H12622JV also boasts wide capacitance range of 22uF to 350uF, high temperature stability, high ripple current, high ripple voltage resistance and various sizes from 4mm to 34mm.

The working principle of a film capacitor is based on the same principle as an electrolytic or ceramic capacitor. However, with film capacitors, the dielectric material is a special film. When an electric charge is applied to the capacitor, the field lines are distributed over the thin film electrode. Thanks to the special geometry of the capacitor, an internal electrical field is then created. This results in a charge field being held between the layers, with the dielectric material acting as the insulator and preventing the electrodes from shorting out.

The range of applications for the ECW-H12622JV includes high frequency power converters, inverter power supplies, electronic ballasts, brushless motor drivers, and solar converters. They are also well-suited to applications with high AC and pulse operations and high switching frequencies, as their high ripple current and peak voltage can efficiently handle the large voltage fluctuations. ECW-H12622JV capacitors can also be used in motor drives, UPS systems, lighting, automotive and power conditioning equipment.

Due to their wide range of applications and their ability to withstand high temperatures, Panasonic’s ECW-H12622JV film capacitors are the perfect choice for a variety of needs. The dielectric material used in these capacitors is designed to provide a high level of long-term reliability, making them an ideal choice for use in high frequency power converters and other demanding environments.
