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.

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
