Thin-film Inductor Can Handle 2.6A In Smartphones

TDK Corporation has unveiled new thin-film inductors particularly for smartphones and other battery-powered devices which require inductors with compact dimensions, low-loss, and high current levels. Applications range includes smartphones and tablet PCs, HDDs, SSDs, digital still and video cameras, portable game consoles, compact power supply modules, etc.

The TFM160808ALC comes with a maximum DC resistance of 62 mΩ that is claimed to be 30 percent lower than for existing types.

Key features of the product include compact dimensions of 1.6 x 0.8 x 0.8 mm, a high rated current of 2.6 A and an inductance of 0.47 μH.

The firm stressed that the required power supply voltage for smartphones and tablet PCs has risen in order to support their increasing multifunctionality, and with this, the number of inductors needed in power supply circuits is likewise growing. These components must be small in size, support a high current levels and, particularly important for smartphones and other battery-powered devices, have low losses.

According to TDK, leveraging its newly developed metal core, the thin-film inductor features lower losses. As a result, the component’s 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 percent.

Mass production of the TFM160808ALC will commence in January 2017. TDK says it will further expand its thin-film inductor lineup with 2.0 x 1.6 mm and 2.0 x 1.25 mm, to address a wider variety of equipment designs.
