DATA SHEET
MINIATURE SIGNAL RELAY
EC2 SERIES
COMPACT AND LIGHTWEIGHT, SMALL MOUNTING SIZE,
HIGH BREAKDOWN VOLTAGE
DESCRIPTION
The EC2 series has reduced mounting space but sustained high-performance of NEC EA2 series. Furthermore,
it complies with 2500 V surge-voltage requirement of Bellcore specification.
FEATURES
Compact and light weight
2 form c contact arrangement
Low power consumption
Reduced mounting space : 15 mm × 7.5 mm
High-breakdown voltage of coil to contacts :
1500 Vac, 2500 V (rise time : 2 µs, fall time : 10 µs)
Capable of High-power switching :
700 Vac, 4.2 A, 4 times in case of accident
UL recognized (E73266), CAS certified (LR46266)
APPLICATIONS
Electronic switching systems, PBX, terminal equipment, telephone systems.
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.

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. 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.
