TDK’s offerings span four major categories, marketed under brands including TDK, EPCOS, InvenSense, Micronas, Tronics, and TDK-Lambda:
Passive Components (Flagship Line)
Capacitors: Multilayer ceramic chip capacitors (MLCCs), aluminum electrolytic capacitors, film capacitors, and Mega Cap automotive-grade MLCCs.
Inductive Devices: Ferrite cores, power inductors, high-frequency inductors, and common-mode chokes/filters.
Others: Piezoelectric components (PowerHap actuators, PiezoListen speakers), circuit protection devices (PTC thermistors, high-voltage contactors), and RF components.
Sensor & Sensor Systems
MEMS Sensors: Inertial measurement units (IMUs), gyroscopes, accelerometers (via InvenSense), and MEMS microphones.
Specialty Sensors: Magnetic sensors, temperature sensors (PTC), pressure sensors, and surface potential sensors.
Solutions: Camera modules with voice coil motors (VCM) and optical image stabilizers (OIS), as well as custom sensor systems for IoT and automotive applications.
Magnetic Application Products
Core Components: High-performance ferrite cores, transformers (IGBT/FET drivers), and magnetic shielding materials.
Embedded Tech: SESUB (Semiconductor Embedded in Substrate) modules for ultra-compact power supplies and Bluetooth devices.
Energy Application Products
Batteries: Lithium-ion batteries (via ATL), solid-state batteries, and battery management systems (BMS).
Power Supplies: Industrial-grade AC/DC power modules and high-voltage DC contactors (e.g., HVC50 for 1500V traction and ESS).
Key Application Fields
Products serve three high-growth sectors:
Automotive: ADAS sensors, battery management, powertrain electronics, and in-vehicle infotainment.
ICT & Consumer: Smartphones, wearables, IoT devices, and data center infrastructure.
Industrial & Energy: Renewable energy systems, industrial automation, robotics, and energy storage systems (ESS).
