Taiyo Yuden Announces Small Wire-Wound Chip Inductors for IC Input Power Circuits

Taiyo Yuden (U.S.A.), Inc. announced that its new LBMF1608 series wire-wound chip inductors are now being produced at the rate of 10 million units per month. As a device that achieves a 47µH inductance rating in 0603 case size (1.6 x 0.8 x 0.8mm), the LBMF1608 is 33% smaller by volume than equivalent-rated 0805 inductors typically used in the IC input power circuits of cell phones, PDAs, still/video cameras and other mobile digital equipment. The LBMF1608 series also provides a 51% smaller footprint and 64% lower profile than 0805 case size (2.0 x 1.25 x 1.25mm) devices – while retaining the same low dc resistance (RDC) and high-inductance characteristics of the larger-size component.

The steadily expanding global market for feature-rich mobile digital equipment is driving the demand for higher performance from smaller size, in terms of both the end device and its component parts. In response to this critical downsizing need, Taiyo Yuden has developed one of the smallest wire-wound chip inductors yet devised for IC input power circuit applications – the LBMF1608 series. The driving force behind the successful 0603 implementation was the company's engineering goal of completely eliminating all space that did not directly contribute to device performance. Other key refinements included optimizing the material compound ratios of the outer covering, redesigning the ferrite core and refining device thickness, shape and the number of windings.

As with other Taiyo Yuden inductors, the LBMF1608 series' non-polarized electrodes simplify manufacturability by allowing the device to be mounted, right side up, regardless of orientation. A total of six part numbers are currently offered in the LBMF1608 series. Sample prices run $0.30 each, with the product being immediately available in production and delivery. ARO is two weeks.
