2. Specifications
1) Standard type (12 V coil voltage)
Notes: *1. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
*2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. For details, please refer to the
“Automotive Relay Users Guide”.
Please inquire our sales representative if you will be using the relay in a high temperature atmosphere (110°C 230°F)
2) Standard type (24 V coil voltage)
Note: All other specifications are the same as those of standard type (12 V coil voltage)
3) Heat resistant type (12 V and 24 V coil voltage)
Notes: 1. All other specifications are the same as those of standard type (12 V coil voltage)
2. *Current value in which carry current is possible when the coil temperature is 180°C 356°F

1. Soldering
Max. 350°C 662°F (solder temperature), within 3 seconds
(soldering time)
The effect on the relay depends on the actual PC board used.
Please verify the PC board to be used.
2. Usage, transport and storage conditions
1) Ambient temperature, humidity, and air pressure during
usage, transport, and storage of the relay:
(1) Temperature: –40 to +85°C –40 to +185°F (Standard type)
–40 to +125°C –40 to +257°F (High heat-resistant type)
(2) Humidity: 2 to 85% RH (Avoid icing and condensation.)
(3) Air pressure: 86 to 106 kPa
The humidity range varies with the temperature. Use within the
range indicated in the graph below.
