WFC02R48S15

Product Data Sheet 2 WATT REGULATED WIDE INPUT RANGE DC/DC CONVERTER WFC02R DESCRIPTION The WFC02R is a family of high performance DC/DC converters that offers regulated outputs over input voltage ranges of 9-36V and 18-72V while offering a wide operating temperature range of -40°C to +85°C without derating. Each WFC02R contains input filtering to minimize conducted noise. The design utilizes surface mounted components, including magnetics, to provide enhanced reliability. The converter is designed to meet the requirements of EN60950 with the “L” pinout having 1,500 VDC isolation. All WFC02R converters are designed to withstand input voltage transients to 200% of nominal input voltage. An additional feature is the ability of the WFC02R to drive high capacitive loads.
