R1SE/H2
UL-60950-1 Certified
Description
The R1SE/H2 series are 1W unregulated DC/DC converters that are lower cost than equivalent
converters. The benefits of high volume production and semi-automatic assembly allow for a lower
selling price without sacrificing our high quality standards. They are UL certified for safety, offer
reasonable efficiency and still meet the full industrial operating temperature range of -40° to +100°C.
All converters are 100% tested in production and carry our 3-year warranty.

Notes:
Note1: Max. capacitive load is defined as the capacitive load that will allow start up in under 1
second without damage to the converter.
Notes:
Note2: Measurements are made with a 100nF MLCC across output. (low ESR)
