| DATA S H E E T MINIATURE SIGNAL RELAY ED2/EF2 SERIES Ultra-low power, compact and lightweight, High breakdown voltage, Surface mounting type DESCRIPTION NEC's new miniature signal relays, ED2/EF2 series, achieved 50 mW of ultra low power consumption. FEATURES TM Low power consumption (50 mW) TM Applicable for the surge voltage standard of FCC (1500 V, 10 x 160 s) and BELLCORE (2500 V, 2 x 10 s) TM Two types for through-hole mounting (ED2 series) and surface mounting (EF2 series) TM Variation of dense mounting type and/or long-joint-life type for latest SMT * Compatible configuration and terminal allocation with dense mounting type of EE2 series * Upgraded soldering joint reliability between the relay terminal and PCB by optimization of the terminal configuration; 20-year-joint-life under 35C-per-day-temperature-difference specified in IPC-SM-785 for telecommuication equipment APPLICATIONS Electronic switching systems, PBX, terminal equipment, telephone system, instrumental equipment. 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. The information in this document is subject to change without notice.

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 mVdc, 10 A. This value is a reference value in the resistance load. Minimum capacity changes depending on switching frequency and environment temperature and the load. 12 DATA SHEET ER0304EJ2V0DS00 ED2/EF2 SERIES DATA SHEET ER0304EJ2V0DS00 13 ED2/EF2 SERIES 14 DATA SHEET ER0304EJ2V0DS00 ED2/EF2 SERIES DATA SHEET ER0304EJ2V0DS00 15 ED2/EF2 SERIES No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this document. 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 antifailure 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, 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. |
