TAIYO YUDEN Expands Lineup of Multilayer Metal Power Inductors for Smartphones
20% improvement in DC superposition characteristics and 10% reduction in DC resistancecompared to previous models

TOKYO, July 24, 2024 — TAIYO YUDEN CO., LTD. has begun mass production of three products,
including the LSCND1412FETR47ME (1.4 x 1.2 x 0.65 mm; maximum height shown), in its MCOIL™
LSCN series of multilayer metal power inductors.
These power inductors are for use as choke coils in the power circuits of smartphones. Retaining thesame form factor as our previous product "LSCND1412FETR47MC" (1.4 x 1.2 x 0.65 mm), the DC
superposition allowable current of our new "LSCND1412FETR47ME" has been increased by 20% to 3.6 A(previously 3.0 A), and its DC resistance has been reduced by 10% to 38 mΩ (previously 42 mΩ). These
improvements contribute to boosting the performance of power supply circuits in smartphones, which arebecoming increasingly sophisticated and multifunctional.
Mass production of these products commenced in May 2024 at our subsidiary WAKAYAMA TAIYOYUDEN CO. LTD. (Inami-cho, Hidaka-gun, Wakayama Prefecture, Japan). Samples are available for 50
yen per unit.
Technology Background
Smartphones are becoming increasingly sophisticated, with capabilities such as AI-based image and video
editing, as well as voice and text translation. At the same time, there is demand for greater efficiency in orderto keep their body small, and achieve long operating times with limited battery capacity. To achieve both highperformance and high efficiency, a smartphone’s processor operates at high speeds with low voltage and highcurrent, and employs a multi-core configuration where each core is equipped with its own power supply
circuit, allowing it to improve both its processing power and efficiency by switching the cores used dependingon load. This trend in power supply circuits has become particularly pronounced in cutting-edge smartphones,
which require both high performance and high efficiency, and in recent years has led to an increase in theadoption of small and thin low-inductance power inductors capable of handling large currents.
To address these needs, at TAIYO YUDEN we have been using metallic magnetic materials with highDC superposition characteristics to optimize the design and other aspects of our MCOIL™ LSCN series
multilayer metal power inductors—which have the advantage of allowing them to be made more compact andthinner—commercializing three products, including “LSCND1412FETR47ME,” which deliver 20% greater
DC superposition allowable current and 10% smaller DC resistance compared to our previous products.

In response to market needs, we will continue to expand and improve our product lineup with higher
functionality and reliability, as well as smaller and thinner products.
