EM1 Series Data

Features

The new NEC TOKIN EM1 series is PC-board mount type and suitable for lamps, C-R circuits, heaters, fans and pumps, etc. controls application in the automobiles which require high quality and high performance.

The EM1 series have higher switching performance than current relays; EP1, ET1 and EX1 series.
  • Suitable for large inrush current load, such as lamps, and C-R circuits, etc.
  • Large current capacity (54A 1hour at 20°C)
  • High heat resistance
  • Flux tight housing
  • Pb free
  • Through-hole refl ow soldering available

APPLICATION

  • Lamp control
  • C-R circuit control
  • Heater control
  • Motor control such as fans and pumps

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” (9600RSGVOL11E1003N1) before dose designing your relay applications.
