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
TM Operating ambient temperature up to +125°C (EP2 / EP1 : +85°C) TM Suitable for motor and solenoid reversible control TM High performance and productivity by unique structure TM Flux tight housing
APPLICATIONS
TM Power window control TM Power sunroof TM Wiper system

Tr1 Tr2 100 ms min.
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.
