ECW-H20402HVB

Film capacitors are commonly used in electrical circuits, because they offer a wide range of electrical and mechanical characteristics. The ECW-H20402HVB is a film capacitor manufactured by Nichicon Corporation, as part of the ECW product family. It is a radial-leaded metallized polyvinylidene fluoride (PVDF) film capacitor with a voltage rating of 250V.

The ECW-H20402HVB has various applications. It can be used for bypassing and decoupling, as the metallized film construction provides high ESR values while maintaining good capacitance characteristics in a wide range of temperatures. It is useful for AC/DC conversion, because of its ability to handle high frequencies with low ESRs. The capacitor is also useful for voltage division, as its size and precision construction make it suitable for high-precision applications. In pulse power supplies, the capacitor can be used to remove high frequency noise, due to its self-resonant frequency. It is also useful for power factor correction in switch mode power electronics.

In addition to its various applications, the ECW-H20402HVB film capacitor also has excellent electrical characteristics. It has a high insulation resistance, low leakage current, and low dissipation factor, making it ideal for high-frequency AC circuits. It also has a high current capacity, allowing it to handle high-current inductive loads. The reliability of the capacitor is also improved by its metallized film construction, which increases its electrical and mechanical robustness.

The ECW-H20402HVB also has a wide temperature range of operation, from -25°C to +85°C. This allows the capacitor to be used in a variety of environmental conditions. The operating temperature range also enhances the capacitor’s lifespan and reliability.

The working principle of the ECW-H20402HVB is based on the same principles as all film capacitors. As electricity passes across its terminals, an electric field develops. This electric field causes a physical movement, which generates a current in the capacitor. This current is then stored in the capacitor’s dielectric material, allowing it to be released at a later time. The magnitude of the current will depend on the capacitance, resistance, and voltage applied to the capacitor.

In conclusion, the ECW-H20402HVB is a film capacitor manufactured by Nichicon Corporation. It is a reliable and versatile component, making it ideal for a wide range of applications. It offers excellent electrical characteristics, a wide operating temperature range, and a wide range of mechanical properties. The working principle of the capacitor is based on the electric field developed when electricity passes across its terminals.
