Overview
The Panasonic ECQ-UV is a Class X2 dual-rated safety film capacitor designed for across-the-line interference suppression in AC-powered equipment. The capacitor features metallized polyester dielectric construction with flame-retardant plastic case and non-combustible resin, making it suitable for noise filtering in a wide range of electrical and industrial applications. Rated for 250VAC with capacitance range from 0.001 to 1.0µF, the ECQ-UV meets both UL/CSA and European safety standards for Class X2 safety-rated components.
