TDK has developed four new series of low-profile, thin-film metal power inductors, featuring up to twice the rated current and half the DC resistance of comparable ferrite inductors.
The new TDK TFM family is available in four form factors, including IEC 1608, which at 1,6 x 0,8 x 1,0 mm is the world’s smallest metal power inductor. The other case sizes in the lineup are 2520, 2016 and 2012. The new parts feature inductances ranging from 0,47 μH to 2,2 μH and rated currents from 0,8 A to 4,0 A.
While the core material of inductors is predominantly ferrite, TDK has harnessed its proprietary materials technology to create a magnetic metal with high saturation flux density, enabling excellent electrical properties in a very compact component.
Compared to the previous ferrite type (TFC252010/2,2 μH), for example, the rated current has been doubled without sacrificing extremely stable DC superposition characteristics.
Thanks to their high rated current, small footprint and low profile, the TFM thin-film metal power inductors are well suited for use in the
DC-DC converters that serve as power supplies in smartphones, tablet PCs and mobile devices.
