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.

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 250C 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
A.
This value is a reference value in the resistance load.
Minimum capacity changes depending on swiching frequency and environment temperature and the load.

may appear in this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellec-
tual 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 particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment, au-
dio and visual equipment, home electronic appliances, machine tools, personal electronic equip-
ment 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 de-
signed 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.
