AUTOMOTIVE RELAYS
EP2F/ EP1F SERIES
HIGH HEAT RESISTIVITY
DESCRIPTION
The NEC EP2F / EP1F series are PC-board m ount type autom otive relays suitable for various m otor controls
and other applications that require a high level of quality and perform ance.
The operate tem perature 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 tim es
com pared with that of EP2 / EP1 series.
FEATURES
™ Operating am bient tem perature up to +125˚C (EP2 / EP1 : +85˚C)
™ Suitable for m otor and solenoid reversible control
™ High perform ance and productivity by unique structure
™ Flux tight housing
APPLICATIONS
™ Power window control
™ Power sunroof
™ Wiper system

It is necessary to take m ore than 100 m sec intervals for on / off tim ing between driving Tr1 and Tr2. If the interval
is less than 100 m sec, an excessive current happen to flow to the relay contacts.
