This series is ideal for use in rugged, thermally challenged applications requiring baseplate cooled operation such as military systems, RF/power amplifiers, commercial avionics and industrial control. All RO products are normally manufactured using a tin-lead soldering process. The MICROVERTER (R) 164 Series is also available in both full RoHS compliant (utilizing lead free solder) and full tin-lead (no pure tin) configurations. All models are designed to meet international safety standards.
