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. Read the cautions described in NEC's "Miniature Relays" (ER0046EJ∗) before dose designing your relay application.
