Film Capacitors

Film capacitors are a type of capacitor which uses a thin plastic film as a dielectric, combining it with an electrode which is most commonly a metal. Film capacitors offer very low ESR and ripple current capability, which makes them ideal for demanding power processing applications. The film capacitor range includes non-inductive, shrinkable and non-shrinkable versions and can handle extremely high temperatures and large ripple currents.

ECW-HA3C123HQ Application Field and Working Principle

The ECW-HA3C123HQ is a non-inductive, shrinkable film capacitor. It is part of the higher voltage ECW-HA series which are designed for harsh operating environments operating up to 450 VDC. The ECW-HA3C123HQ is designed for a wide range of high-voltage applications and allows for predictable, stable and reliable performance over long periods of time. The ECW-HA3C123HQ is designed for use in high-voltage applications such as solar inverter, wind inverter, battery packs, and DC/DC converters. It is designed to maximize the filter size in power supply enclosures and to minimize EMI/RFI noise emissions. The ECW-HA3C123HQ can also be used in high-efficiency switch mode power supplies, power supplies for welding, plasma cutting applications, and high-voltage DC/DC converter circuits.

The working principle of the ECW-HA3C123HQ is similar to that of other film capacitors. This type of capacitor uses a thin plastic film as a dielectric, which is then combined with an electrode – usually a metal, like copper or aluminum. The dielectric film is designed to reduce the amount of current which leaks through the capacitor, improving its energy storage capabilities. The resulting capacitor is able to store excessive energy, supporting larger electrical current levels and smoother power conversions.

The ECW-HA3C123HQ is rated at 45nF 450VDC. This rating indicates that the device has a maximum voltage of 450 volts and a capacitance of 45 nanofarads. The device is capable of handling a large ripple current of up to 6.33 Arms and is capable of operating at temperatures up to +125℃. The ECW-HA3C123HQ is also designed with non-inductive construction, which makes it suitable for high-voltage AC applications.

Overall, the ECW-HA3C123HQ is a great choice for a wide range of high-voltage applications, thanks to its low ESR and ripple current capability, long-term stability and reliability, and the ability to operate in harsh environments. The device\'s non-inductive construction makes it well-suited for AC applications and its 45nF 450VDC rating provides a generous amount of energy storage.
