Japan-based TAIYO YUDEN CO., LTD. has begun mass production of a new metal power inductor: the MCOIL LSCN series of multilayer metal power inductors, the "LSCND1005CCTR47MH" (1.0 mm x 0.5 mm x 0.33 mm).
This power inductor is ideal for use as choke coils in the power supply circuits of wearable devices, such as smartphones, augmented reality (AR)/virtual reality (VR) glasses, true wireless stereo (TWS) devices and smart watches. The LSCND1005CCTR47MH is 40% lower in height than the previous product, the LSCNB1005EETR47MB (1.0 mm x 0.5 mm x 0.55 mm), and realizes a metal power inductor as thin as 0.33 mm. This will contribute to the miniaturization and thickness reduction of cutting-edge electronic devices.
Mass production of this product began at the company's subsidiary, WAKAYAMA TAIYO YUDEN CO., LTD. (Inami-cho, Hidaka-gun, Wakayama Prefecture), in December 2024. Samples are available for 50 yen ($0.35) per unit.

Technology background
As smartphones, AR/VR glasses and wearable devices are equipped with higher-performance processors, more sensors, multiple cameras and higher-capacity batteries for sophistication, electronic components used in them need to be smaller and thinner.
In particular, smartphones are requiring thinner electronic components, due to the trend toward foldable devices that combine large screens and smaller sizes, as well as the adoption of multi-layered circuit boards. On the other hand, wearable devices, such as AR/VR glasses, TWS devices and smart watches require smaller, lighter and thinner components to achieve a thin profile and comfortable fit.
To address these needs, TAIYO YUDEN has been expanding its lineup in the MCOIL LSCN series of multilayer metal power inductors which use metallic magnetic materials with high DC saturation characteristics, and provide superior characteristics for achieving miniaturization and thinness. With this latest upgrade, the company has commercialized the LSCND1005CCTR47MH, which achieves a thickness of 0.33 mm for a metal power inductor by utilizing the strengths of our multilayer process technology.
In response to market needs, TAIYO YUDEN will continue to expand and improve its product lineup with higher performance and reliability.
