Core Product Series of TDK Specialty Electronic Components
TDK’s lineup covers five key specialty component categories, each tailored to specific functional requirements and application scenarios:
Switching / Heating Components:High-efficiency switching elements and heating solutions for industrial control and automotive systems. Flagship products include the TDK EPCOS Thyristors & Triacs (switching components) with voltage ratings up to 1600V and current handling up to 40A, ideal for AC power control in industrial motor drives and HVAC systems. Heating elements (PTC Heating Components) feature self-regulating temperature control (50°C–200°C), low power consumption, and AEC-Q200 compliance, suitable for EV battery preheating and in-vehicle climate control. All variants offer fast response times and resistance to vibration/thermal shock.
Piezo Components:High-performance piezoelectric actuators, sensors, and transducers for precision motion and sensing. The TDK Piezo Actuator Series delivers sub-micron positioning accuracy (≤0.1µm) and high force density (up to 10N), used in industrial robotics, medical diagnostic equipment, and precision optical systems. Piezo sensors (Pressure & Vibration Piezo Sensors) offer wide measurement ranges (0–1000 bar pressure, 0–200g vibration) and operating temperatures from -40°C–150°C, compatible with harsh industrial and automotive environments. Additionally, piezo buzzers (a subset of piezo components) provide clear audio feedback with low power consumption.
Contactors:Compact, high-reliability contactors for power switching in automotive and industrial systems. The TDK Automotive Contactors (AEC-Q200 compliant) support voltage ratings up to 800V DC and current up to 200A, designed for EV powertrains, battery management systems (BMS), and charging stations. Industrial contactors (EPCOS Series) feature IP67 protection, low contact resistance (<5mΩ), and long mechanical life (≥10 million operations), suitable for renewable energy inverters and factory power distribution.
Buzzers:Miniaturized acoustic components for audio feedback and alert systems. TDK offers electromagnetic buzzers (ESD Series) and piezo buzzers (PZT Series) with sound pressure levels (SPL) from 60dB–110dB (at 10cm) and operating voltages of 3V–24V. Automotive-grade buzzers comply with ISO 16750 vibration standards, used in in-vehicle warning systems (seatbelt alerts, low battery) and ADAS notifications. Consumer electronics variants (surface-mount, 4.5mm×4.5mm mini size) are ideal for smartphones, wearables, and home appliances.
Microphones:High-sensitivity MEMS (Micro-Electro-Mechanical Systems) microphones for audio capture in consumer and industrial devices. The TDK InvenSense MEMS Microphone Series offers signal-to-noise ratio (SNR) up to 78dB, frequency response 20Hz–20kHz, and low power consumption (≤100µA). Automotive-grade microphones (AEC-Q103 compliant) support in-vehicle voice recognition and noise cancellation, while consumer variants are used in smartphones, tablets, and smart speakers. Industrial models feature IP54 protection for harsh environment audio monitoring.
Key Features of TDK Specialty Electronic Components
TDK’s switching, piezo, contactor, buzzer, and microphone solutions share core advantages that address critical industry pain points:
High Reliability & Durability: Operate in extreme temperature ranges (-40°C–150°C), resist vibration (up to 50g peak) and moisture (IP54–IP67), and offer long operational lifespans (≥10 million cycles for contactors, ≥5000 hours for heating elements).
Industry-Specific Compliance: AEC-Q200/Q103 (automotive), ISO 13485 (medical), IEC 61810 (contactors), and RoHS/REACH certifications ensure compatibility with global sector regulations.
Compact & Energy-Efficient Design: Miniaturized footprints (down to 4.5mm×4.5mm for buzzers, 2.75mm×1.85mm for MEMS microphones) and low power consumption optimize space and energy use in portable and automotive devices.
Precise Performance: Sub-micron accuracy for piezo actuators, high SNR for microphones, and fast switching response (<1µs for thyristors) ensure consistent, high-quality functionality.
Easy Integration: Standardized surface-mount (SMD) and through-hole packages, plus compatibility with common circuit interfaces (I2S for microphones, PWM for buzzers), simplify PCB design and system integration.
Application Fields
TDK’s specialty electronic components are integral to functional systems across high-demand sectors:
Automotive & Transportation: EV powertrain switching, battery preheating (heating components), in-vehicle alerts (buzzers), voice recognition (microphones), BMS contactors, and ADAS acoustic feedback systems.
Industrial Automation: Factory robotics (piezo actuators), motor control (switching components), power distribution (contactors), equipment warning systems (buzzers), and harsh environment audio monitoring (industrial microphones).
Consumer Electronics: Smartphones/tablets (MEMS microphones, mini buzzers), wearables (low-power heating elements, micro buzzers), smart speakers (high-SNR microphones), and home appliances (switching controls, alert buzzers).
Medical Devices: Precision surgical robotics (piezo actuators), medical equipment heating (PTC components), patient monitoring alerts (buzzers), and diagnostic device audio capture (high-accuracy microphones).
Renewable Energy: Solar/wind inverter power switching (thyristors), energy storage system contactors, and equipment warning systems (buzzers).
