Tolerance of inductance :

20%.

 

2.

Irated is the DC current

which cause the inductance drop less than 25% of its nominal inductance without current

 

and the surface temperature of the part increase

less than 45oC.

3.

Operating temperature: -20oC to 105oC (including

self-temperature rise).
