Description
The RP15-SOFW 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,
the RP15-SOFW converters are fully specified 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-S0FW series will find many uses in telecommunications and other
demanding applications where price, board space or board height is at a premium.
