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. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Please refer to Usage ambient
condition in CAUTIONS FOR USE OF AUTOMOTIVE RELAYS.
*3. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you conrm operation under actual conditions.
