Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. Wave is standard shock voltage of ±1.2×50μs according to JEC-212-1981
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.

NOTES
1. For cautions for use, please read “GENERAL APPLICATION GUIDELINES”.
Note about relay installation orientation
Top
When installing with the relay terminals parallel to the ground, the contact terminals at
the bottom and the coil terminals at the top, component friction will occur after
numerous switching actions or due to vibration in the non-excitation state.
Since this may cause the relay to stop functioning when the pick-up voltage increases
even if the nominal voltage is applied, please do not install using this orientation.
