TDK Corporation
TDK Corporation is a Tokyo, Japan-based global electronics company founded in 1935 with approximately $14 billion in annual revenue, and one of the most diversified magnetic technology companies in the world — producing magnetic sensors, passive components, power supplies, piezo materials, and energy devices under brands including TDK, EPCOS, Micronas, and InvenSense. Within the magnetic sensing space, TDK’s Micronas division is a leading producer of automotive-grade 3D magnetic sensors and programmable angle sensor ICs — including the widely specified HAL series — used for motor commutation, throttle and pedal position, gear selector, and EPS applications, while its general magnetic sensor portfolio covers TMR angle sensors, AMR sensors, current sensors, and Hall effect switches for industrial and consumer markets. TDK is also the world’s largest producer of ferrite cores and components, a manufacturer of NdFeB and SmCo magnets through its TDK-EPC division, and a producer of MRAM chips — making it one of the few companies in the world with deep materials science, magnetic sensing, and magnetic storage capabilities all under one corporate umbrella.
