ECW-F(D) Metallized Plastic Film Caps Panasonic ECW Series Metallized Plastic Film Capacitors are now available in ECW-F(D) 450VDC. The ECW-F(D) are designed for DC applications that do not require a significant amount of pulse current, and for power factor correction and residential electronics applications. The built-in fuse function, combined with the small case size, make them appropriate for any application requiring DC linkage. Panasonic ECW Series Metallized Plastic Film Capacitors are small, low loss polypropylene capacitors with excellent frequency characteristics and low hum. The capacitors are available in 250VDC, 450VDC, and 630VDC, and 800VDC with a capacitance range from 0.1µF to 6.8µF (250VDC, 450VDC, and 630VDC), and from 0.010µF to 0.047µF (800VDC).
