AUTOMOTIVE RELAY. ET1F-B3M1S Datasheet
HIGH HEAT RESISTIVITY
The new NEC TOKIN 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.
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
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/TOKIN's "Miniature Relays" (0123EMDD03VOL01E) before dose
designing your relays applications.
