The MICROVERTER 164 Series is a second generation product
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
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
safety standards.
