The upper operation ambient temperature limit is the maximum temperature that

can satisfy the coil temperature rise value.

Pick-up and drop-out voltages increase approximately 0.4% for each 1 C

where the standard temperature is 20 C

where the ambient temperature is high, please take into consideration the rise in

pick-up voltage due to ambient temperature and determine a coil nominal voltage

that is within the maximum allowable voltage range.

and desired reliability level, therefore it is recommended to check this with the

actual load.
