Description
1 Watt
SMD
Dual Independent
Outputs
The R1DA 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 power 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:
E358085
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
