TEMPERATURE BEHAVIOR

Br TEMPERATURE COEFFICIENT* % / °C -0,10 / -0,12
HcJ TEMPERATURE COEFFICIENT* % / °C -0,40 / -0,78

*The temperature coefficients are nominal reference values only. They can vary for different temperatures and don’t need to be linear.

**The maximum operating temperature depends on the magnet shape, size and on the specific application. Maximum working temperature data shown on the catalogue are based on the international standard B/H = Pc > 0,7.
