Miniature Signal Relays
UA2/UB2 Series
Overview
The KEMET UA2/UB2 miniature signal relays offer a super
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.
