Miniature Signal Relays
UC2/UD2 Series
Overview
Applications
The KEMET UC2/UD2 miniature signal relays offer a super
compact case size in a flat 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.
• Electronic switching systems
• PBX
• Terminal equipment
• Telephone systems
Benefits
• Low power consumption (< 140 mW)
• Super compact and lightweight
• Flat package for dense mounting
• Low magnetic interference
• Tube or embossed tape and reel packaging
• UL recognized (E73266) and CSA certified (LR46266)
• Surface mount and through-hole options
