| 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 -40C through +125C. By this high heat resistivity, the contact carrying current of EP2F / EP1F series at 25C increases 1.3 or 1.4 times compared with that of EP2 / EP1 series. FEATURES TM Operating ambient temperature up to +125C (EP2 / EP1 : +85C) 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 EP2F SERIES EP1F SERIES Document No. ER0145EJ1V0DS00 Date Published December 1995 M Printed in Japan (c) 1995 EP2F / EP1F SERIES SCHEMATIC (BOTTOM VIEW) EP2F SERIES 2 4 1 39 4 1 EP1F SERIES 2 3 4 2 1 3 8 56 7 10 56 7 8 5 [Unit A] [Unit B] [Unit A] [Unit B] [H Bridge Type] [Separate Type] DIMENSIONS mm (inch) EP2F SERIES H Bridge Type Vent hole JAPAN Separate Type Separate type discrimination mark Vent hole JAPAN 2(0.079) Date code Part number Part number EP2F-B3L2 0G3 24 Date code EP2F-B3L2T 0G3 24 23.8 + 0.5 - (0.94) 0.5(0.02) 16.0 + 0.5 - (0.63) 16.2 + 0.5 - (0.64) 23.8 + 0.5 - (0.94) 0.5(0.02) 16.0 + 0.5 - 16.2 + 0.5 - (0.64) 3.5 (0.14) 3.5 10.1 8.0 5.45 (0.21) (0.21) (0.4) (0.31) 3.5 (0.14) (0.32) (0.32) 10.1 8.0 5.45 (0.21) (0.4) (0.31) 3.5 (0.14) 2-0.5x1.1(0.02x0.04) 3.1 (0.12) 4 -0.5x1.1(0.02x0.04) 2.2 (0.09) 3.1 (0.12) 5.45 (0.21) 6.4 (0.25) 5.45 (0.09) (0.21) 6.4 (0.25) (0.14) (0.63) 2.2 (0.09) (0.14) 3.5 (0.31) (0.4) (11.9) 3.1 (0.12) 2.2 (0.09) 8.0 10.1 (11.9) 2 -1.3x1.3(0.05x0.05) 4 - 0.6( 0.22) for reference (0.14) 3.5 (0.31) (0.4) (11.9) 8.0 10.1 (11.9) 2 -1.3x1.3(0.05x0.05) 4 - 0.6( 0.22) for reference 2 (0.32) (0.32) 8.1 8.1 8.1 8.1 2.2 6.4 EP2F / EP1F SERIES EP1F SERIES Vent hole JAPAN Date code Part number EP1F-B3G1 4A 1 22 14.6 + 0.5 - (0.58) 16.2 + 0.5 - (0.63) 16.0 + 0.5 - 3.5 0.5(0.02) 10.1(0.4) 8.0(0.31) 2- 0.6 ( 0.02) 3.5 (0.14) 3.1 (0.12) (0.21) 2.2 (0.09) 5.45 (0.25) 6.4 2.65 (0.1) (0.14) (0.63) 1.3x1.3 (1.5x1.5) 2-0.5x1.1 (0.02x0.02) for reference PCB PAD LAYOUT mm (inch) (BOTTOM VIEW) EP2F SERIES 4 - 1.1 +0.1 ( 0.043) -0 2 - 1.5 +0.1 ( 0.059) -0 4 - 1.1 +0.1 ( 0.043) -0 4 - 1.5 +0.1 ( 0.059) -0 EP1F SERIES 2 - 1.1 +0.1 -0 ( 0.043) 2 - 1.5 +0.1 -0 ( 0.059) 1.9 +0.1 -0 ( 0.075) 2 - 1.9 +0.1 ( 0.075) -0 [H Bridge Type] [Separate Type] 2 - 1.9 +0.1 ( 0.075) -0 3 EP2F / EP1F SERIES SPECIFICATIONS Items Contact Form Contact Material Contact Resistance Contact Switching Voltage Contact Switching Current Contact Carrying Current EP2F 1 form Cx2 (H bridg type and separate type) Silver oxide complex alloy 50 m max.

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. 5 EP2F / EP1F SERIES TECHNICAL DATA Coil Temperature (EP2F-B3L1) Coil Temperature Rise (C) Vcoil = 12 V, IC = 25 A Vcoil = 7.5 V, IC = 25 A 100 Coil Temperature Rise (C) 150 100 50 50 Vcoil = 12 V, IC = 0 A Vcoil = 7.5 V, IC = 0 A IC = 0A 0 10 20 30 0 0.5 1.0 1.5 2.0 Energized Time (minutes) Applied Power (W) Operate Time (EP2F-B3L1) ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Mean ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Release time (EP2F-B3L1) 10 Operate Time (ms) 10 Release Time (ms) 5 5 With Diode ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Mean ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Without Diode 0 0.5 1.0 1.5 0 0.5 1.0 1.5 Applied Power (W) Applied Power (W) 6 EP2F / EP1F SERIES 7 EP2F / EP1F SERIES No part of this document may be copied in any form or by any means without the prior written consent of NEC Corporation.
