DATA S H E E T AUTOMOTIVE RELAYS EQ1 SERIES DESCRIPTION The new NEC EQI Series automotive relays are designed for motor and lamp control applications that require a high level of quality and performance. The EQ1 has a unique two-piece design for the magnetic circuit, which result in small size, light weight, and high productivity. FEATURES ™ PC board mounting ™ Same pin-layout as MR301 ™ Approx. 70% Iess relay volume than MR301 ™ Approx. 80% Iess relay space than MR301 ™ Approx. 90% Iess relay height than MR301 ™ Approx. 60% Iess relay weight than MR301 APPLICATIONS ™ Motor control ™ Heater control ™ Solenoid control ™ Lamp control EQ1 SERIES For Proper Use of Miniature Relays DO NOT EXCEED MAXIMUM RATING Do not use relay under excessive conditions such as over ambient temperature, over voltage and over current. Incorrect use could result in abnormal heating and damage to the relay or other parts. READ CAUTIONS IN THE SELECTION GUIDE.

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, customer 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, 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, Iife 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 NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
