DC BAIS (A)
1. Tolerance of inductance : 1.5~100uH 30%.
2. Irated is the DC current which cause the inductance drop 35% of its nominal inductance without current
and the surface temperature of the part increase less than 45^oC.
3. Operating temperature: -20^oC to 105^oC (including self-temperature rise).
