1) The shown temperature coefficients are nominal reference values only . They can vary for different temperatures and don't need to be linear.
2) The maximum operating temperature is depending on the magnet shape, size and on the specific application.
The above plotted graphs are idealized and represent theoretical values of the material. Shown are curves according nominal values based
on uncoated material samples according to IEC 60404-5. Material and magnetic data represent typical data that may vary due to product
