NOTES
1. Usage, transport and storage
conditions
1) Ambient temperature, humidity, and
atmospheric pressure during usage,
transport, and storage of the relay:
(1) Temperature:
–40 to +85C –40 to +185F
(Standard type)
–40 to +110C –40 to +230F
(High heat-resistant type)
(2) Humidity: 2 to 85% RH
(Avoid freezing and condensation.)
(3) Atmospheric pressure: 86 to 106 kPa
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.

2. Storage condition after opening a
moisture-prevention package
(1) After opening a moisture-prevention
package, use the item as soon as
possible (within 3 days under an
environment of Max. 30C 86F, Max.
70% RH).
(2) If products are not used within 3 days
after opening a moisture-prevention
package, store them in a humiditycontrolled desiccator or in a storage bag
with silica gel.

• Cautions for mounting operations
Temperature profile indicates the
temperature of the soldered part (*1) of
terminals on the surface of a circuit
board. The exterior temperature of a
relay may be extremely high depending
on the component density on the board
or the heating method of the reflow oven
or circuit board type. Sufficient
verification under actual processing
conditions is required.
2) Avoid cleaning (ultrasonic cleaning,
boiling cleaning, etc.) and coating in
order to prevent negative impacts on
relay characteristics.
For Cautions for Use, see Relay Technical Information.
