The catalog says "The operating temperature is between -40°C to +85°C, but there are cases where this can vary depending on the material.” Does this mean that it can be used at over +85°C when there is quite a margin with the Curie temperature?

The catalog says “operating temperature: –30 to +105°C” and gives a storage temperature that is lower stating “storage temperature: –30 to +85°C”, but isn’t it the opposite?
