MINIATURE SIGNAL RELAY
ED2/EF2 SERIES
Ultra-low power, compact and lightweight, High breakdown voltage,
Surface mounting type
DESCRIPTION
NEC's new miniature signal relays, ED2/EF2 series, achieved 50 mW of ultra low power consumption.
FEATURES
™ Low power consumption (50 mW)
™ 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 mounting (ED2 series) and surface mounting (EF2 series)
™ Variation of dense mounting type and/or long-joint-life type for latest SMT
• Compatible configuration and terminal allocation with dense mounting type of EE2 series
• Upgraded soldering joint reliability between the relay terminal and PCB by optimization of the terminal
configuration;
20-year-joint-life under 35˚C-per-day-temperature-difference specified in IPC-SM-785 for telecommuication
equipment
APPLICATIONS
Electronic switching systems, PBX, terminal equipment, telephone system, instrumental equipment.
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's "Miniature Relays" (ER0046EJ∗) when you choose relays
for your application.
