DATA SHEET
AUTOMOTIVE RELAYS
EP2F/EP1F SERIES
HIGH HEAT RESISTIVITY
DESCRIPTION
The NEC EP2F / EP1F series are PC-board mount type automotive relays suitable for various motor controls
and other applications that require a high level of quality and performance.
The operate temperature range for EP2F / EP1F series is –40˚C through +125˚C.
By this high heat resistivity, the contact carrying current of EP2F / EP1F series at 25˚C increases 1.3 or 1.4 times
compared with that of EP2 / EP1 series.
FEATURES
™ Operating ambient temperature up to +125˚C (EP2 / EP1 : +85˚C)
™ Suitable for motor and solenoid reversible control
™ High performance and productivity by unique structure
™ Flux tight housing
APPLICATIONS
™ Power window control
™ Power sunroof
™ Wiper system

It is necessary to take more than 100 msec intervals for on / off timing between driving Tr1 and Tr2. If the interval
is less than 100 msec, an excessive current happen to flow to the relay contacts.
