Low-loss inductor for power supply circuits

9 November 2016 Passive Components

TDK’s new TFM160808ALC thin-film inductor is intended for power supply circuits, and features a maximum DC resistance of 62 mΩ – 30% lower than for existing types (e.g. TFM160808ALM, 0,47 μH). The new type, whose compact dimensions are just 1,6 x 0,8 x 0,8 mm, also offers a high rated current of 2,6 A and an inductance of 0,47 μH.

Thanks to a newly developed metal core, the thin-film inductor features lower losses. As a result, its efficiency over a broad output current range of 10 mA to 2,5 A is higher than that of existing types and can improve the efficiency of DC-DC converter power supplies by nearly 1%.

In the future, TDK will expand its lineup of thin-film inductors for power supply circuits to include components with footprints of 2,0 x 1,6 mm and 2,0 x 1,25 mm, making the series suitable for a wider variety of equipment designs.
