DESCRIPTION
The EB2 series is a version of the EA2 series, suitable for surface mounting with infrared soldering (lRS) and
vapor phase soldering (VPS). This series has three variations of high solder joint reliability type, and low profile
type.
FEATURES
TM Compact and lightweight : 7.5 mm
14.3 mm
9.3 mm, 1.5 g
TM 2 form c contact arrangement
TM Low power consumption
TM Low magnetic interference
TM Breakdown voltage: 1 000 VAC (surge voltage 1 500 V), FCC Part 68 conformable
TM UL recognized (E73266), CSA certified (LR 46266)
TM Lineup in non-latch, single-coil latch and double-coil latch types
TM Lineup in minimum footprint (9.3
14.3), and high solder joint reliability (20 years) types
TM Lineup in low profile type (hight : 6.5 mm), and Ultra-low profile (hight : 5.6 mm)
APPLICATIONS
Electronic switching systems, PBX, key telephone systems, automatic test equipment and other electronic equipment.
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.

Note
Test by pulse voltage

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.
