Miniature Signal Relays
EC2/EE2 Series
Overview
Applications
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.
• Electronic switching systems
• PBX
• Terminal equipment
• Telephone systems
Benefits
• Low power consumption (< 200 mW)
• Compact and lightweight
• Low magnetic interference
• Tube or embossed tape and reel packaging
• UL recognized (E73266) and CSA certified (LR46266)
• Surface mount and through-hole options
• High Breakdown Voltage (NKX) type can withstand 1.5
kVAC at open contacts
