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
