1. Tolerance of inductance :
K : 10 % for 0.12~100uH.
2. Irated is the DC current which cause the inductance drop less than 10% of its nominal inductance without current
and the surface temperature of the part increase less than 45 C.
3. Operating temperature: -20 C to 105 C (including self-temperature rise).
