For immediate release
TAIYO YUDEN Launches the Automotive Power Inductors LAXH Series
Designed for high temperatures up to 150°C, and suitable for choke coils and filters in powertrains

TOKYO, February 9, 2023—TAIYO YUDEN CO., LTD. has announced today the launch of the AEC-Q200(reliability qualification test standard for automotive passive components) qualified LAXH series of ferrite
power inductors, and has begun the mass production of 16 items including the LAXHG6060YEL1R0NMR(6.0x6.0x4.5mm).
These products are designed for choke coils and noise filters for DC-DC converters, which are power
supply circuits used in automobile engines, transmissions, and other powertrain components.
The LAXH series adopts a sleeveless structure with its advantageous compact size and high current
capacity, and the upper limit of its operating temperature range has been raised to 150°C from that of ourexisting LCXH series (operating temperature range: -40°C to +125°C).
Furthermore, by applying our metal material technology and using metal material for the outer resin,
the series delivers a large current capacity at a DC saturation allowable current of 13.5A (inductance value1.0μH), or twice that of our existing LAYP series "LAYPH06045DL1R0NGA" (6.3x6.0x4.5mm, inductancevalue 1.0μH, DC saturation allowable current: 6.7A) with an operating temperature limit of 150℃.
Production of the products commenced at our overseas subsidiary company, TAIYO YUDEN(PHILIPPINES), INC. (Lapulapu City, Cebu, the Philippines) in January 2023, with a sample price of 150
yen per unit.
Technology Background
Recently, new vehicles have been equipped with an ever-greater number of electronic control units, typified
by ADAS units. This requires a greater number of power supply circuits, which boosts the demand for power
inductors used inside them. In particular, ECUs are increasingly being installed in high-temperature engine
compartments, and the electronic components installed must be able to handle high temperatures.
In response to these needs, TAIYO YUDEN has adopted a sleeveless structure with its advantageouscompact size and high current capacity, and applied the metal materials technologies it has nurtured in its
metal power inductors “MCOIL™” to commercialize this LAXH series which delivers an operating
temperature limit of 150℃, and large current capacity at a DC saturation allowable current of 13.5A(inductance value 1.0μH).
TAIYO YUDEN focuses on the development of products that meet market needs, and will continue toexpand its power inductor product lineup.

470± 200.450.382.76*1 The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at20℃)*2 The temperature rise current value (Idc2) is the DC current value having temperature increase up to 40℃.
(at 20℃)*3 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. Derate the current to use byreferring to the following graph.
