New dual winding inductors for high current applications

With dual windings the package is suited to a broad range of applications including DC-DC single-ended primary-inductor converters (SEPIC), non-isolated voltage regulators, point of load modules, LED drivers and I/O filter chokes. The HM78D-1210 models offer inductance values from 4.7 to 470µH in parallel configuration; 18.8 to 1880µH in series.

Low resistance values ensure high-efficiency designs for SEPICs, whilst the high current ratings enable designers to save space on the PCB. Maximum DC resistance ranges from 0.014 to 0.57ohm with leads connected in parallel, 0.056 to 2.28ohm in series. In parallel, rated current is from 1.22 to 10.6A, with saturation currents 1.8A to 18.0A. Equivalent ratings in series mode are half these values.

Housed in a rugged package the lead-free devices feature shielded construction to enhance EMI performance. Operating temperature ranges from -40°C to +125°C and the inductors are supplied in tape-and-reel format for automated production.
