Film capacitors belong to the class of dielectric capacitors and their component structure is similar to that of plastic film capacitors. The ECW-U2334KCV is a film capacitor series and it can be used in various applications. The ECW-U2334KCV differs from plastic film capacitors with respect to stability, rate of ageing, dielectric strength and other properties. In this article, the application field and working principle of the ECW-U2334KCV will be discussed.

Application Field

The ECW-U2334KCV is mainly used in the fields of switch-mode power supplies, active power filter circuits, uninterruptable power supplies and power converters. It can provide stable output voltages and currents even under extreme conditions. The series is also suitable for applications in industrial and medical electronics, power conversion equipment, automation and other related industries. Furthermore, the wide range of working temperatures (from -25°C to +125°C) makes it suitable for environments where temperature variations are common.

The product offers eight voltage options (6.3V, 8V, 8.2V, 10V, 16V, 25V, 50V and 100V) and capacitance values from 470pF to 47μF. Additionally, it is also available in radial and SMD packages, which can save space and ease mounting. The SMD package is compliant with lead-free process requirements, while the radial package is lead-free and halogen-free. This means that the series is environment friendly and can be used in high safety level applications.

Working Principle

The ECW-U2334KCV is an aluminium metallized film capacitor series with a self healing type dielectric. The internal structure of this series mainly contains an insulation film layer and two electrodes. The insulation film layer is constructed of two aluminium sheets that are interlaced with each other. The two electrodes are composed of tin-plated copper alloy wires.

When applying a voltage to the capacitor, a negative charge will be attracted to the insulation film layer, which in turn immobilizes any charge that has leaked from the insulation film layer. Once the voltage is applied, the electrodes will move up and down and a capacitance is created. The capacitance depends on the number of insulation film layers and the interweaving pattern between them. The higher the number of layers, the greater the capacitance.

The insulation film layer ensures that the capacitor can operate reliably over a wide temperature range with very low losses. The self-healing properties of the insulation layer also make it suitable for applications in high voltage environments. Furthermore, the series can be used in circuits without the need for additional components, since it is already equipped with thermal and electrical protection. All of these features make the ECW-U2334KCV series an ideal choice for any application where performance, reliability and safety are important.

Conclusion

The ECW-U2334KCV is an aluminium metallized film capacitor series with a self healing type dielectric. It is suitable for switching-mode power supplies, active power filter circuits, uninterruptable power supplies and power converters. The series is also suitable for applications in industrial and medical electronics, power conversion equipment, automation and other related industries. The wide range of voltage and capacitance options, and its ability to withstand extreme temperatures make it suitable for high safety level applications. With its reliable performance, wide range of options and self healing properties, the ECW-U2334KCV series is definitely a good choice for many different applications.
