Contributes to miniaturization and high
performance with high-density mounting in
high-temperature environments such as in automobiles
TOKYO, July 18,
2024 /PRNewswire/ -- TAIYO YUDEN CO.,
LTD. has commercialized four items, including the
multilayer 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.
World's First Multilayer Metal Power
Inductor Capable of Withstanding Temperatures up to 165°C.
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 by enabling 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 per unit.
The advancements that we have seen in recent years in electronic
controls in production vehicles, as typified 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 and integrate them into single modules. Components
mounted at high densities become more susceptible to the effects of
heat, as their reduced volumes makes it more difficult for the heat
generated by the components to dissipate. Furthermore, since ECUs
are increasingly being installed in engine compartments—a high
temperature 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, and launched 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 to
expand its power inductor product lineup.

*2 The saturation current value (Idc1) is the DC current value
having inductance decrease down to 30%. (at 20℃)
*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 and temperature rise current
value.
* Derating of rated current is necessary depending on the ambient
temperature. Please see our website below for detailed
specifications.
