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 EP2F SERIES Document No. ER0145EJ1V0DS00 Date Published December 1995 M Printed in Japan EP1F SERIES © 1995 EP2F / EP1F SERIES SCHEMATIC (BOTTOM VIEW) EP2F SERIES EP1F SERIES 2 3 2 1 4 4 8 5 6 [Unit A] 2 3 9 1 1 10 7 [Unit A] [H Bridge Type] 4 8 5 6 [Unit B] 3 7 5 [Unit B] [Separate Type] DIMENSIONS mm (inch) EP2F SERIES H Bridge Type Separate Type Separate type discrimination mark Vent hole JAPAN φ 2(0.079) Part number 0G3 24 (0.14) 3.5 (0.31) (0.4) (11.9) 8.0 10.1 (11.9) ∗ for reference (0.63) (0.14) 0.5(0.02) 4 - φ 0.6( φ 0.22) 5.45 (0.21) 4 -0.5×1.1(0.02×0.04) (0.14) 3.5 (0.31) (0.4) (11.9) 8.0 10.1 (11.9) 8.1∗ 8.1∗ (0.32) (0.32) 2.2 (0.09) 3.1 (0.12) 5.45 (0.21) 6.4 (0.25) 3.5 (0.14) 3.1 (0.12) 2.2 (0.09) (0.21) 6.4 (0.32) (0.32) 8.1∗ 8.1∗ 5.45 (0.09) (0.21) 6.4 (0.25) 2 -1.3×1.3(0.05×0.05) (0.4) (0.31) 16.0 + – 0.5 16.2 + – 0.5 (0.64) 3.5 (0.14) 0.5(0.02) 16.0 + – 0.5 (0.63) 3.5 2.2 (0.09) 5.45 (0.21) 3.5 (0.14) 10.1 8.0 2-0.5×1.1(0.02×0.04) 2.2 (0.4) (0.31) 23.8 + – 0.5 (0.94) 16.2 + – 0.5 (0.64) 3.1 (0.12) 10.1 8.0 Date code EP2F-B3L2T 0G3 24 23.8 + – 0.5 (0.94) 2 Part number Date code EP2F-B3L2 Vent hole JAPAN 2 -1.3×1.3(0.05×0.05) 4 - φ 0.6( φ 0.22) ∗ for reference EP2F / EP1F SERIES EP1F SERIES JAPAN Vent hole Date code EP1F-B3G1 Part number 4A 1 22 16.2 + – 0.5 (0.63) 16.0 + – 0.5 (0.63) 3.5 (0.14) 0.5(0.02) 14.6 + – 0.5 (0.58) 2.65∗ (0.1) 10.1(0.4) 8.0(0.31) 3.5 6.4 1.3×1.3 (1.5×1.5) (0.25) 3.1 (0.12) (0.14) (0.21) 2.2 (0.09) 5.45 2- φ 0.6 ( φ 0.02) ∗ for reference 2-0.5×1.1 (0.02×0.02) PCB PAD LAYOUT mm (inch) (BOTTOM VIEW) EP2F SERIES 4 - φ 1.1 +0.1 – 0 ( φ 0.043) EP1F SERIES 2 - φ 1.5 +0.1 – 0 ( φ 0.059) 4 - φ 1.1 +0.1 – 0 ( φ 0.043) 2 - φ 1.1 +0.1 –0 ( φ 0.043) 2 - φ 1.5 +0.1 –0 ( φ 0.059) 4 - φ 1.5 +0.1 – 0 ( φ 0.059) φ 1.9 +0.1 –0 ( φ 0.075) 2 - φ 1.9 +0.1 – 0 ( φ 0.075) [H Bridge Type] 2 - φ 1.9 +0.1 – 0 ( φ 0.075) [Separate Type] 3 EP2F / EP1F SERIES SPECIFICATIONS at 25 ˚C (77 ˚F) Items EP2F EP1F Contact Form 1 form C×2 (H bridg type and separate type) Contact Material Silver oxide complex alloy Contact Resistance 50 mΩ 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) Coil Temperature Rise (˚C) 150 Vcoil = 12 V, IC = 25 A Vcoil = 7.5 V, IC = 25 A 100 50 Vcoil = 12 V, IC = 0 A 100 50 I C = 0A Vcoil = 7.5 V, IC = 0 A 10 0 20 0 30 0.5 Energized Time (minutes) Operate Time (ms) 5 0 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Mean ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 0.5 1.0 Applied Power (W) 6 1.5 2.0 Release time (EP2F-B3L1) 1.5 10 Release Time (ms) Operate Time (EP2F-B3L1) 10 1.0 Applied Power (W) 5 With Diode ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Mean ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Without Diode 0 0.5 1.0 Applied Power (W) 1.5 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.
