MINIATURE SIGNAL RELAY
ED2/ EF2 SERIES
Ultra-low pow er, com pact and lightw eight, High breakdow n voltage,
Surface m ounting type
DESCRIPTION
NEC's new m iniature signal relays, ED2/EF2 series, achieved 50 m W of ultra low power consum ption.
FEATURES
™ Low power consum ption (50 m W)
™ Applicable for the surge voltage standard of FCC (1500 V, 10 × 160 µs) and BELLCORE (2500 V, 2 × 10 µs)
™ Two types for through-hole m ounting (ED2 series) and surface m ounting (EF2 series)
™ Variation of dense m ounting type and/or long-joint-life type for latest SMT
• Com patible configuration and term inal allocation with dense m ounting type of EE2 series
• Upgraded soldering joint reliability between the relay term inal and PCB by optim ization of the term inal
configuration;
20-year-joint-life under 35˚C-per-day-tem perature-difference specified in IPC-SM-785 for telecom m uication
equipm ent
APPLICATIONS
Electronic switching system s, PBX, term inal equipm ent, telephone system , instrum ental equipm ent.
For Right Use of Miniature Relays
DO NOT EXCEED MAXIMUM RATINGS.
Do not use relays under exceeding conditions such as over am bient tem perature, over voltage
and over current. Incorrect use could result in abnorm al heating, dam age to related parts or
cause burning.
READ CAUTIONS IN THE SELECTION GUIDE.
Read the cautions described in NEC's "Miniature Relays" (ER0046EJ ) when you choose relays
for your application.
