Printed in Japan
Ultra-low power, compact and lightweight, High breakdown voltage,
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.
NEC TOKIN's new miniature signal relays, ED2/EF2 series, achieved 50 mW of ultra low power consumption.
Electronic switching systems, PBX, terminal equipment, telephone system.
Low power consumption (50 mW)
Applicable for the surge voltage standard of FCC (1500 V, 10 × 160 µs) and Telcordia (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
telecommuication equipment
