NOTES
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.
