Delta Electronics SMT Power Inductor SIQ1048 Series User manual

1. Tolerance of inductance: 1.0~1.8uH 30% , 2.8~470uH 20%.
2. Irated is the DC current which cause the inductance drop 20% typical of its nominal inductance without current
and the surface temperature of the part increase less than 45
oC.
o
3. Operating temperature: -20 C to 105 (including self-temperature rise).
