Description
The RP15-SOF series are SMD open frame ultraminiature power DC/DC converters in
a case half the size of
industry standard 15W converters. The converters use
solder ball pins to enable SMD mounting and can be reflow soldered.
Despite their small size, these converters are fully specified devices with output
currents up to 3.5 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-SOF series will find many uses in telecommunications and
other demanding applications where cost, board space or board height is at a
premium.
