Delta Electronics SMT Power Inductor SIR74 Manual, Specification Sheet

1. Tolerance  of  inductance:   20%  for  10~27uH,    15%  for  33~68uH.
2. Irated  is  the  DC  current  which  cause  the  inductance  drop  10%  typical  of  its  nominal  inductance  without  current
    and  the  surface  temperature  of  the  part  increase  less  than  45
3. Operating  temperature : -20 to  105 (including  self-temperature  rise).
