Surface Mount
Terminations
Using EMC’s patented asymmetrical wrap geometry (U.S.
Patent # 5,739,743), the thermal dissipation of the surface
mount terminations is improved by increasing the
solderable terminal area. This eliminates the need for bolt
down heat sinks and tabs, reducing assembly costs.
