Thin-film power inductors developed by TDK for automotive use offer enhanced current capacity.
**TDK Unveils High-Performance Thin-Film Power Inductors for Automotive Applications**
TDK Corporation, a global leader in electronics, has announced the expansion of its TFM201612BLEA series of thin-film power inductors, specifically tailored for automotive power circuits with demanding requirements for high current, low loss, and compact size. This development marks a significant leap in performance for passive components in automotive electronics.
Key Technical Improvements
The new TFM201612BLEA series offers several key technical improvements over previous models:
1. Higher Current Handling: The new inductors support up to 5.6 A, a 16% increase over previous models, enabling their use in higher-power automotive applications without increasing component footprint. 2. Lower DC Resistance: A 31% reduction in DC resistance (to 22 mΩ) means less energy is lost as heat, directly improving power supply circuit efficiency. 3. Compact Size: The inductors maintain a compact 2.0 x 1.6 x 1.2 mm package, essential for fitting into the constrained spaces of automotive electronic control units (ECUs) and other modules. 4. High Reliability: Designed for automotive environments, these inductors operate reliably up to 150°C, essential for under-hood and other high-temperature applications. 5. Production Status: Mass production began in July 2025, marking commercial readiness for automotive OEMs and tier suppliers.
Optimised for Automotive Power Circuits
TDK’s new thin-film power inductors are optimised for several critical automotive systems, including electric vehicles (EVs), advanced driver assistance systems (ADAS), automotive camera modules, cellular vehicle-to-everything (V2X), and general automotive power circuits.
