DATA SHEET
MINIATURE SIGNAL RELAY
UC2/UD2 SERIES
Ultra-small package, Low profile, Surface mounting type
DESCRIPTION
NEC TOKIN's UC2/UD2 relay is a new generation miniature signal relays of super compact and low profile package.
FEATURES
• Small mounting size and low profile package.
• Telcordia (2500 V surge coil to contacts) and FCC (1500 V) surge capability.
• IEC60950/UL1950/EN60950 spacing and high breakdown voltage.
(Basic insulation class on 200 V working voltage)
• Low power consumption 140 mW
APPLICATION
Electronic switching systems, PBX, terminal equipment, telephone.
For Right Use of Miniature Relays
DO NOT EXCEED MAXIMUM RATINGS.
Do not use relays under exceeding conditions such as over ambient temperature, over voltage and over current.
Incorrect use could result in abnormal heating, damage to related parts or cause burning.
READ CAUTIONS IN THE SELECTION GUIDE.
Read the cautions described in NEC/TOKIN's "Miniature Relays" when your choose relays for your application.
