1. Tolerance of inductance: 15% for 3.9~8.2uH, 10% for 10~47uH.

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 o C.

3. Operating temperature : -20 o C to 105 o C (including self-temperature rise).
