DATA SHEET
AUTOMOTIVE RELAYS
EU2 SERIES
DESCRIPTION
The new NEC TOKIN EU2 series is PC-board mount type and suitable for various motor and solenoid controls
application in the automobiles which require high quality and high performance.
The EU2 series is the ultra low profile SMD relay. The EU2 series is succeeding in about 75% of low profiling in
comparison with the ET2 series which is low profile type. And itʼs basic characteristics are same as the EX2 series
which is miniature and high performance.
FEATURE
・Twin type (Two relays in one housing)
・SMD
・Low profile ( Approx. 75% relay height of ET2, Approx. 57% relay height of EX2)
・Light weight (Approx. 80% relay weight of ET2, Approx. 94% relay weight of EX2)
・Pb free
・Tape & Reel packaging
APPLICATION
・Motor control
・Solenoid 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 NECʼs “Miniature Relays” (9600RSGVOL11E1003N1) before dose designing
your relay applications.
