DATA SHEET
MINIATURE SIGNAL RELAY
EB2 SERIES
COMPACT AND LIGHT WEIGHT
SURFACE MOUNTING TYPE
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
Compact and lightweight : 7.5 mm × 14.3 mm × 9.3 mm, 1.5 g
2 form c contact arrangement
Low power consumption
Low magnetic interference
Breakdown voltage: 1 000 VAC (surge voltage 1 500 V), FCC Part 68 conformable
UL recognized (E73266), CSA certified (LR 46266)
Lineup in non-latch, single-coil latch and double-coil latch types
Lineup in minimum footprint (9.3 × 14.3), and high solder joint reliability (20 years) types
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.
The information in this document is subject to change without notice.

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. Ultrasonic cleaning is not recommended to keep contact performance reliable. Alcohol-based solvents are
available as proper solvents.
4. Pressurized stress on the relay cover may affect reliable operation.
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.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use of such
device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual
property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its electronic components, the
possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising
from a defect in an NEC electronic component, customers must incorporate sufficient safety measures in its design, such
as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer
designated "quality assurance program" for a specific application. The recommended applications of a device depend on
its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particu-
lar application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual
equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-
crime systems, safety equipment and medical equipment (not specifically designed for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems
or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact
an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
