DATA SHEET
MINIATURE SIGNAL RELAY
UA2/UB2 SERIES
Super-compact size, Slim-package, Surface-mounting type available
DESCRIPTION
NEC TOKIN's UA2/UB2 relay ia a new generation miniature signal relay of super-compact size and slim-pakage.
FEATURES
Small mounting size of slim package for dense mounting.
Telcordia (2500 V) 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
APPLICATIONS
Electronic switching systems, PBX, terminal equipment, telephone system.
For Correct 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 you choose relays for your application.
