For immediate release
TAIYO YUDEN: World's First Multilayer Metal Power Inductor Capable of Withstanding
Temperatures up to 165°C
Contributes to miniaturization and high performance with high-density mounting in hightemperature environments such as in automobiles

TOKYO, May 30, 2024 ―TAIYO YUDEN CO., LTD. has commercialized four items, including themultilayer metal power inductor MCOIL™ "LACNF2012KKTR24MAB" (2.0 x 1.25 x 1.0 mm, maximum
height value shown), which complies with the "AEC-Q200" reliability qualification test standard for passive
automotive components. Through advancements made in our proprietary metal materials and multilayer
construction methods, we have achieved an upper operating temperature limit of 165°C for a multilayer metal
power inductor, a world’s first*1.
These products are used as choke coils in DC-DC converters used in automotive engine ECUs, control
systems such as BMS, safety systems such as ABS, body-related systems such as ADAS, and information
systems such as instrument clusters.
By extending the upper operating temperature limit range of our conventional product"LCCNF2012KKTR24MAD" (operating temperature range: -55°C to +150°C) to 165°C, these new products
are able to contribute to the miniaturization and performance enhancement of power supply circuits byenabling high-density mounting in high-temperature environments such as in automobiles.
Mass production of these products began at our subsidiary, WAKAYAMA TAIYO YUDEN CO., LTD.
(Inami-cho, Hidaka-gun, Wakayama Prefecture, Japan), in April 2024. Samples are available for 50 yen perunit.
The advancements that we have seen in recent years in electronic controls in production vehicles, astypified by ADAS units, has led to a greater number of power supply circuits on vehicles, which in turn has
led to growth in the demand for power inductors that are used in these circuits. Furthermore, performance also
continues to improve through functional integration, such as in integrated cockpits that combine instrument
clusters and infotainment devices. While the throughput of IC chips continues to grow as these devices
become increasingly multifunctional and high-performance, there is also a growing need to make on-board
electronic components smaller and thinner in order to arrange devices in highly dense configurations andintegrate them into single modules. Components mounted at high densities become more susceptible to theeffects of heat, as their reduced volumes makes it more difficult for the heat generated by the components todissipate. Furthermore, since ECUs are increasingly being installed in engine compartments—a hightemperature environment—on-board electronic components must be able to withstand high temperatures.

To address these challenges, TAIYO YUDEN further improved the reliability of the MCOIL™ LCCN
series of multilayer metal power inductors, which had the advantage of being smaller and thinner, andlaunched the AEC-Q200 certified LACN series which provides an extended operating temperature range of 55°C to +165°C.
TAIYO YUDEN focuses on the development of products that meet market needs, and will continue toexpand its power inductor product lineup.

*2 The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at20℃)*3 The temperature rise current value（Idc2) is the DC current value having temperature increase up to 40℃.
(at 20℃)*4 The rated current is the DC current value that satisfies both of current value saturation current value andtemperature rise current value.
* Derating of rated current is necessary depending on the ambient temperature. Please see our website below
