MinebeaMitsumi Inc. is a top precision mechatronics technology and electronic component manufacturer in Japan and even globally, headquartered in Tokyo. The company was established in 2017 through the merger of Meibeiya Group and Sanmei Group. With decades of technological accumulation and global layout, it has now become a comprehensive technology giant spanning the fields of consumer electronics, automotive industry, energy, and the Internet of Things. In 2023, the company further strengthened its global competitiveness in the power electronics field by acquiring Hitachi Power Semiconductor Device, Ltd.
Core Business and Product Matrix
Meibeiya Sanmei takes "precision technology driven innovation" as its core, and its product line covers the following key areas:
Precision Machinery and Micro Components:

Motors and actuators: including ultra-thin vibration motors (for smartphones), stepper motors (for industrial robots), and brushless DC motors (for electric vehicles).
Electronic components and sensors:
Sensor solutions: temperature, pressure, optical sensors, supporting automotive ADAS and industrial automation.
Wireless communication module: Bluetooth, Wi Fi, 5G module, empowering smart homes and IoT devices.
Power Semiconductor and Energy Systems (newly added segment after Hitachi's acquisition and integration):
IGBT module: for electric vehicle (EV) inverters, photovoltaic inverters, and industrial frequency converters.
Silicon carbide (SIC) devices: high-voltage, high-performance semiconductors used in fast charging piles and renewable energy systems.
Power management IC: Optimizing energy conversion efficiency, serving data centers and smart grids.
Mechatronics integrated system:
Automotive electronic units: automotive ECU, electric power steering (EPS) motor, onboard charger.
Intelligent device components: laptop backlit keyboard, camera autofocus module, etc.
Strategic Expansion: Hitachi Power Semiconductor Acquisition
In 2023, Meibeiya Sanmei completed the acquisition of Hitachi's power semiconductor division for approximately 80 billion yen. This acquisition not only acquired Hitachi's leading high-voltage IGBT and silicon carbide chip technology, but also integrated its wafer manufacturing facility located in Ibaraki Prefecture, Japan. This move significantly enhances the company's core technology reserves in the fields of electric vehicles, renewable energy, and industrial energy management, forming synergies with existing motor and sensor businesses, and helping customers achieve their carbon neutrality goals.
