Small SMT power inductors handle up to 59 A

The MLC7532, MLC7542, and MLC7540 shielded high-current power inductors offer Isat ratings up to 59.2 A and DC resistance down to 1.2 mΩ in a small 0.295 x 0.276 inch package. The iron core devices operate over –40° to 80°C with specified maximum current.

Package height is 0.126, 0.157, or 0.165 inches and inductance values are from 0.01 to 2.17 µH with I_rms ratings from 24.9 to 8.4 A, with a 20°C temperature rise. Inductance drop is 20% (typical) for currents of 38.0 to 8.3 A. The inductor SRF is 670 to 91 MHz and DCR is from 1.20 to 11.7 mΩ. From $0.78 ea/1,400.
