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
TM PC board mounting
TM Same pin-layout as MR301
TM Approx. 70% Iess relay volume than MR301
TM Approx. 80% Iess relay space than MR301
TM Approx. 90% Iess relay height than MR301
TM Approx. 60% Iess relay weight than MR301
APPLICATIONS
TM Motor control
TM Heater control
TM Solenoid control
TM Lamp control
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.
