CE MARK
The PFKC03 series offer 3 watts of output power from a package in an IC compatible 24
pin DIP configuration without derating to 71潞C ambient temperature and pin to pin
compatible to PFKC05,FKC03,FKC05 series. PFKC03 series have 2:1 wide input
voltage of 4.5-6, 9-18, 18-36 and 36-75VDC. PFKC03 features 1600VDC of isolation and,
short-circuit protection and suffix 鈥淗鈥?can get 3000VDC isolation. All models are
particularly suited to telecommunications, industrial, mobile telecom and test equipment
applications.
