ECQ-U2A683KL

Film capacitors have played a vital role in the wide range of industrial equipment like generators, motors, transformers and other electronic devices for over 50 years. The most commonly used type of film capacitor is the ECQ-U2A683KL, which has extensive applications and intriguing working principles.

In terms of application fields, ECQ-U2A683KL capacitors mainly include large power equipment such as power modules and high-frequency switching power supplies and motor drives; consumer electronics products such as UPS, communication power supplies and computers; and industrial automation control systems such as grid control and servo motor. Its capacitance range is usually between 100μF~220μF, with a rated power of 168V ~ 450V and a rated temperature of -25°C ~ 85°C.

In terms of its working principle, ECQ-U2A683KL capacitors mainly rely on the relative permittivity of polypropylene film and metal electrode separation. When the load ages or the AC voltage changes, the metal electrode can channel the current to flow through the polypropylene film. As a result, the energy stored in the polypropylene film accumulates until the current stops flowing. This effect not only contributes to providing larger ripple current but also superior heat dissipation.

Moreover, ECQ-U2A683KL capacitors also boast superior characteristics compared to its counterparts, such as higher power density and better vibration endurance. Owing to this, it is an ideal selection for various industrial applications with frequent current and voltage fluctuations.

In short, ECQ-U2A683KL capacitors offer diverse application fields and excellent working principles, making it an increasingly popular choice in mechanical, electrical and electronic industries.
