DC/DC-Converter
Description The R0.25S and R0.25D converters are of the enclosed open frame type, i.e. they are not
potted. The converters are typically used in general purpose and industrial low ower
isolation and voltage matching applications where an SMD converter is required.
The converter series feature an extended ambient temperature operating range of -40°C
to +100°C without derating and optional continuous short circuit protection. In addition
to single, dual and independent outputs, two isolation options and three different case
formats, the converters are also available prepacked as tape and reel for use with
automatic insertion machines.
