The SMT45A-501 from Gowanda Electronics is a Dual Wound Toroidal Inductor. This inductor has an inductance of 5 µH and an inductance tolerance of ±25%.  It has a current rating of 7.21 A and a DCR of 7.3 milli-ohms. This toroidal inductor includes a ferrite core with two windings which allows series or parallel connection depending on whether a higher current or higher inductance is required. It can minimize core loss and function at high frequency with its ferrite core construction. This power inductor is available in a surface-mount package that measures 15.5 x 12.2 x 6.35 mm.
