MINIATURE SIGNAL RELAY
EA2 SERIES
COMPACT AND LIGHTWEIGHT
DESCRIPTION
The EA2 series has reduced package size and power consumption to other NEC Conventional relays.
Furthermore, it complies with 1500 V surge-voltage requirement of FCC part 68 by the unique structure and the
efficient magnetic circuit
FEATURES
™ Low power consumption
™ Compact and light weight
™ 2 form c contact arrangement
™ Low magnetic arrangement
™ Breakdown voltage : 1000 Vac (surge voltage 1500 V), FCC Part 68 compliant
™ Tube packaging
™ UL recognized (E73266), CAS certified (LR46266)
APPLICATIONS
Electronic switching systems, PBX, key telephone systems, automatic test equipment and other electronic equip-
ment.
ATTENTION
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.

The latch type relays should be initalized at appointed position before using, and should be enegized to specific
polanity by a bone polabity to avoid wrong operation.
Any special coil requirement, please contact NEC for availability.

GUIDE TO APPLICATIONS
1. When connecting coils, refer to the pin configuration to prevent misoperation or malfunction.
2. The latch type relay should be initialized at the appointed position (set or reset position) when using, and should
be energized or deenergized to the specified polarity to avoid wrong operations by reversed contact state.
3. Soldering should be done at 250˚C within 10 sec.
4. Ultrasonic cleaning is not recommended to keep reliable contact performance. Alcohol-based solvents are
available as proper solvents.
5. Pressurized stress on the relay cover is not favorable to keep reliable operation of the relay during operation.
6. Minimum contact load of the relay is 10 mV, 10 µA.
This value is a reference value in the resistance load.
Minimum capacity changes depending on swiching frequency and environment temperature and the load.
