Leveraging advanced ceramic, metal-core, and organic material formulations, TDK’s Substrates cover a comprehensive range of solutions—from high-thermal-efficiency ceramic substrates for power electronics to low-loss organic substrates for 5G communication devices. These substrates serve as the core base material for electronic component mounting and signal transmission, playing a pivotal role in automotive electrification, 5G telecommunications, industrial automation, and medical devices. For global procurement needs, partnering with a trusted TDK distributor is essential to guarantee product authenticity, material consistency, and stable supply chains.
Core Product Series of TDK Substrates
TDK’s Substrates lineup spans specialized series tailored to diverse thermal, frequency, and environmental requirements, each optimized for key technical metrics and industry scenarios:
1. Ceramic Substrates (Alumina, Aluminum Nitride)
Flagship solutions for high-thermal-management and high-reliability applications. The TDK ALN series (aluminum nitride ceramic substrates) offers ultra-high thermal conductivity (up to 230 W/m·K), excellent electrical insulation, and operating temperatures up to 1000°C, ideal for power semiconductor modules (IGBT, SiC), EV powertrains, and industrial motor drives. Alumina ceramic substrates (e.g., TDK AL2O3 series) provide cost-effective thermal performance (20–35 W/m·K) and high mechanical strength, suitable for consumer electronics power supplies and automotive electronic control units (ECUs). High-volume procurement of these substrates is typically facilitated via authorized TDK distributor to meet power electronics production demands.
2. Metal-Core Substrates (MCPCB)
Optimized for thermal management in high-power LED and automotive electronics. The TDK MCPCB series (metal-core printed circuit boards) features a copper or aluminum core with thermal conductivity up to 200 W/m·K, effectively dissipating heat from high-power components. Compliant with AEC-Q200 automotive standards, these substrates are ideal for automotive LED lighting, EV battery management systems (BMS), and on-board charger (OBC) modules. They offer excellent solderability and mechanical flexibility, simplifying integration into complex automotive component designs.
3. High-Frequency Organic Substrates
Tailored for 5G, RF, and high-speed signal transmission applications. The TDK RF-35 series (high-frequency organic substrates) offers low dielectric loss (Df ≤0.002 at 10GHz) and stable dielectric constant (Dk = 3.5±0.1), ensuring minimal signal attenuation for 5G base stations, RF front-end modules, and satellite communication devices. Low-profile and lightweight designs enable compact packaging of high-frequency components, making them suitable for 5G CPE (Customer Premises Equipment) and industrial IoT gateways. A qualifiedTDK distributor can provide tailored selection guidance for high-frequency scenario-specific requirements.
4. Automotive-Specific Substrates
Customized for harsh automotive environments and electrification needs. This includes high-temperature ceramic substrates for EV traction inverters (operating up to 250°C), metal-core substrates for in-vehicle LED displays, and low-loss substrates for V2X (Vehicle-to-Everything) communication modules. All automotive substrates meet strict automotive EMC (CISPR 25) and functional safety standards (ISO 26262), ensuring reliable performance in EVs, hybrid vehicles, and traditional internal combustion engine vehicles.
5. Medical-Grade & Industrial Substrates
Specialized for precision medical equipment and extreme industrial conditions. Medical-grade substrates (compliant with ISO 13485) offer biocompatibility and high signal integrity, suitable for medical imaging devices (CT, MRI) and portable diagnostic equipment. Industrial-grade substrates (e.g., TDK IND series) feature corrosion resistance and vibration tolerance (up to 50g peak), ideal for industrial robotics, oil/gas exploration equipment, and renewable energy inverters. These high-precision substrates are exclusively sourced from authorizedTDK distributor to ensure compliance with industry regulations.
