Notes:
❇
1This value can change due to the s witching frequency , en vironmental conditions,
and desired reliability lev el, therefore it is recommended to chec k this with the ac-
tual load.
❇
2The upper limit for the ambient temperature is the maximum temperature that
can satisfy the coil temperature rise. Under the pac king condition, allowab le tem-
perature range is from –40 to +70°C –40°C to +158°F.
