Remark:

1.	MAX.Working Temperature is only for reference,depending on the circuit which the magnet is applications.
2.	When L/D ratio of testing piece is eaqual to 0.7,the open flux irreversible loss at Max.Working Temperature less/eaqual 5% is guaranteed.(Lmeans magnetization direction length,D means diameter of magnetic pole surface.)
3.	Users are recommended to consult us on any application involving temperature near to 150℃.
