Description
The RND series of converters are industry standard, 2” x 1” size, low profile, dual output, DC/DC converters
intended for SMT placement and reflow soldering. The product provides on-board conversion of standard
telecom, datacom and industrial input voltages to isolated low output voltages without the need for any
additional cooling. Proprietary patented manufacturing process ensures optimal quality through full process
automation. The converters are cost effective high performance alternatives to competing products on the
market.

Absolute Maximum Ratings
Product Specifications
Nov 2001
Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect
long term reliability and cause permanent damage to the converter. Specifications apply over specified input
voltage, output load and temperature range, unless otherwise noted.
