The MICROVERTER® 164 Series is a second generation product
which combines high eciency electrical power design and
proprietary advanced thermal management techniques includ-
ing insulated metal substrate technology, specialty dielectrics
and formulated thermally conductive potting to produce small,
ruggedized DC/DC converters with reduced temperature rise
and increased reliability. This series is ideal for use in rugged,
thermally challenged applications requiring baseplate cooled
operation such as military systems, RF/power ampliers, com-
mercial avionics and industrial control. All RO products are
normally manufactured using a tin-lead soldering process. The
MICROVERTER® 164 Series is also available in both full RoHS
compliant (utilizing lead free solder) and full tin-lead (no pure
tin) congurations. All models are designed to meet international
safety standards.
