Panasonic, a worldwide leader in capacitor technology, introduces the NEW ECW-F(A) 250/450 Volt Series Metallized Polypropylene Capacitors for high frequency and power factor correction circuits. The ECW-F(A) Series features Panasonic’s new safety construction for increased capacitor safety. This patterned metallization technology allows current to flow past a failed point bypassing failed cells and therefore increasing capacitor safety. The ECW-F(A) Series miniaturized footprint is the choice for application downsizing where smaller case sizes are required. ECW-F(A) is more than 50% smaller than the ECQ-E(H) and ECW-F(S) Series.
