Miniature Signal Relays
EC2/EE2 Series
Overview
The KEMET EC2/EE2 miniature signal relays offer a compact
case size in a slim package. Minimal board space is consumed
with either a through-hole or surface mount configuration. These
relays are recognized by UL and CSA, while also being compliant
with Part 68 of the FCC’s 1,500 V surge capacity.
