DESCRIPTION
The WPC03R is a family of high performance DC/DC converters that offers regulated outputs over input voltage ranges of 9-18V , 18-36V and 34-72V while offering a wide operating temperature range of -40°C to +85°C without derating. Each WPC03R 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 V DC isolation. All WPC03R converters are designed to withstand input voltage transients to 200% of nominal input voltage. An additional feature is the ability of the WPC03R to drive high capacitive loads.

Specifications typical at TA=25°C, nominal input voltage, rated output current unless otherwise stated. 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.
