TOKYO – TAIYO YUDEN CO., LTD. has commercialized 14 items, including the multilayer metal power inductor MCOIL™ “LACNF1608KKT1R0MAB” (1.6 x 0.8 x 1.0 mm, maximum height shown), which complies with the “AEC-Q200” certification reliability test standard for passive automotive components.
The new product is approximately 49% smaller than our previous product, the “LACNF2012KKT1R0MAB” (2.0 x 1.25 x 1.0 mm), and can contribute to the miniaturization and higher performance of power supply circuits installed in automobiles.
These products are used as choke coils in DC-DC converters used in automotive engine control systems such as ECUs, safety systems such as ABS, body-related systems such as ADAS, and information systems such as instrument clusters.
Mass production of this products began at our subsidiary, WAKAYAMA TAIYO YUDEN CO., LTD. (Inami-cho, Hidaka-gun, Wakayama Prefecture), in December 2025. Samples are available for 50 yen per unit.
Background
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 in order to arrange devices in highly dense configurations and integrate them into single modules. 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.
In response, TAIYO YUDEN has added a new 1608 size to its MCOIL™ LACN series of multilayer metal power inductors, which boast the advantages of being smaller and thinner, and having an operating temperature range of -55°C to +165°C. Our proprietary metal materials are bonded to each other by an oxide film using heat treatment, ensuring insulation and providing high heat resistance and thermal conductivity. Thanks to these features, the product exhibits stable characteristics, is able to withstand high temperatures, and achieves high reliability, even in devices used in harsh temperature environments such as automotive applications.
TAIYO YUDEN focuses on the development of products that meet market needs, and will continue to expand its power inductor product lineup.
