The converters use solder ball pins to enable SMD mount- ing and can be reflow soldered. Despite their small size, the RP15-OFW converters are fully specified Open Frame devices with output currents up to 4 Amps, no minimum load, 2250VDC isolation and low ripple/noise figures. The outputs are also fully protected against short circuits, overcurrent and overvoltage. The RP15-0FW series will find many uses in telecommunications and other demanding applications where Single Output price, board space or board height is at a premium.
