| OBSOLETE PRODUCT Contact factory for replacement model WFC02RC 2 WATT REGULATED WIDE INPUT RANGE DC/ DC CONVERTER FEATURES RoHS Compliant Low Cost, High Performance Small DIP Package Full Power to +85C Extended Temperature Range: -40C to +85C Industry Standard Pinout Full Short Circuit Protection High Capacitive Loading Capability Protected Against High Input Voltage ISO9001 CERTIFIED For full details go to www.murata-ps.com/rohs DESCRIPTION The WFC02RC 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 -40C to +85C without derating. Each WFC02RC 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 WFC02RC converters are designed to withstand input voltage transients to 200% of nominal input voltage. An additional feature is the ability of the WFC02RC to drive high capacitive loads.

They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device's plastic body will not be compromised and internal temperatures within the converter will not exceed 175C. Care should be taken to control manual soldering limits identical to that of wave soldering.
