Operate Data
Must Operate and Must Release Voltage: See Coil Data table.
Initial Operate Time: 7 milliseconds, typical, with rated coil voltage
applied.
Initial Release Time: 2 milliseconds, typical, with zero volts applied (for
unsuppressed relays after having been energized at
rated coil voltage.)
Environmental Data
Temperature Range: Storage: -40°C to +155°C.
Operating: -40°C to +125°C (4).
Shock: 20g, 11 milliseconds, half sine wave pulse.
Vibration: (For NC contacts, NO contacts are significantly higher.)
10-40 Hz., 1.27mm double amplitude.
40-70 Hz., 5 g's constant.
70-100 Hz., 0.5mm double amplitude.
100-500 Hz., 10 g's constant.
Mechanical Data
Termination: 0.250" quick connect and printed circuit terminals.
Enclosures:
Dust Cover: Protects relay from dust. For use in passenger
compartment or enclosures.
Shrouded Dust Cover: Protects relay and relay connector (order
separately) from dust and splash.
Weatherproof Cover: Mates with a connector (order separately) to seal
relay from salt spray etc. Recommended for under
hood application.
Cover Retention: Dust cover will withstand a 33.7 pound (150 Newton)
force (axially applied) without detachment. Ultrasonic
cover: 50 pound (220 Newton).
Weight: 31g (1.1 oz.) approximately (dust cover model).
Abnormal Operation
Overload Current: Consult factory.
24V Jump Start: 24VDC for 5 minutes conducting rated contact current
@ 23°C.
Drop Test: Capable of meeting specifications after a 3.28 foot (1.0 meter)
drop onto concrete.
Flammability: UL94V-0 external; UL94-HB or better, internal parts (meets
FMVSS 302).
Notes
(1) See Figure 1.
(2) Inrush current for lamp load.
(3) Allowable overdrive is rated at ambient temperature for 23°C or 85°C as
stated with no load current flowing through the relay contacts and
minimum coil resistance. Also see Figure 2 for maximum ambient
temperature versus applied coil voltage.
(4) See Figure 2.
(5) Current and times are compatible with circuit protection by a typical
automotive circuit breaker. Relay will make, carry and break the
specified current.

Assumptions:
1. Thermal resistance = 50°C per watt
2. Still air
3. Nominal coil resistance
4. Maximum mean coil temperature = 180°C
5. Coil temperature rise due to load
= 2°C @ 8 amps
= 5°C @ 16 amps
= 11°C @ 24 amps
= 20°C @ 32 amps
= 32°C @ 40 amps
6. Thermal resistance and power dissipation
based on coil resistance at 180°C
7. Curves are based on 1.6 watts at 23°C
8. When full lifetime is at high ambient and high
load current, subtract 25°C from maximum
allowable ambient temperature.
