EMC Technology is the world’s
premier manufacturer of surface
mount, chip, and pill terminations.
EMC invented the original pill
termination (patent 3,354,412) and
holds the patent for the asymmetrical
surface mount termination (patent
5,739,743), allowing for improved
power handling capabilities.
EMC also offers small 0402 and 0505
size full ground plane terminations
with alumina, AlN and BeO
type substrates.
