DATA S H E E T AUTOMOTIVE RELAY ET2F/ET1F SERIES HIGH HEAT RESISTIVITY DESCRIPTION The new NEC ET2F/ET1F series is PC-board mount type automotive relay suitable for various motor and heater control applications that require a high quality and performance. ET2F is a twin relay type and ET1F is a single relay type. The operate temperature range for ET2F/ET1F series is –40˚C through +125˚C. By this high heat resistivity, the contact carrying current of ET2F/ET1F series at 25˚C increases 1.3 to 1.4 times compared with that of ET2/ET1 series. FEATURES ™ Operating ambient temperature up to +125˚C (ET2/ET1 : +85˚C) ™ Suitable for motor and solenoid reversible control ™ High performance and productivity by unique structure ™ Flux tight housing APPLICATIONS ™ Motor control ™ Heater control ™ Solenoid control Type ET2F Type ET1F For Proper 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 and damage to relay or other parts. READ CAUTIONS IN THE SELECTION GUIDE. Read the cautions described in NEC's "Miniature Relays" (ER0046EJ∗) before dose designing your relays applications.

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.
