WFC02RC REV B: RoHS 08/2007Page 1
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 -40°C to +85°C 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.

These devices are intended for wave soldering or manual soldering. 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 260°C 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 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering. THROUGH-HOLE SOLDERING INFORMATION
