Converters
Fully RoHS 10/10 conform
Full power at +100°C ambient temperature
1kVDC/1s isolation
UL60950-1 and IEC/EN60950-1 certified
Suitable for fully automated assembly
(including vapor phase soldering)
Optional continuous short circuit protection
Description
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:
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
