TDK has introduced compact multilayer inductors for enhancing ADAS performance by maintaining efficient power and data transmission through a single cable.
Researchers at TDK Corporation have launched the latest addition to their MLJ1005-G series of multilayer inductors, designed specifically for automotive Power-over-Coax (PoC) circuits. These compact inductors, measuring 1.0mm x 0.5mm, are set to enhance vehicle safety systems by improving signal filtration in advanced driver-assistance systems (ADAS).
Modern ADAS technologies rely on multiple cameras and sensors to ensure safe driving by continuously monitoring the vehicle’s surroundings. Traditionally, these automotive cameras required separate lines for power and data transmission, adding complexity to wiring systems. However, PoC technology simplifies this by transmitting both power and data through a single coaxial cable. This reduces cable requirements, minimises vehicle weight, and contributes to better fuel efficiency and environmental sustainability.
Automotive manufacturers, electronics engineers, and system designers working on ADAS solutions are likely to benefit from these inductors, which address the challenges of integrating compact and efficient filtering components into PoC systems. The inductor series ensures robust signal quality, even as data transmission rates increase, making it ideal for next-generation vehicle designs.
The integration of PoC systems demands robust filtering mechanisms to separate power from data signals effectively. The company’s inductor series addresses this challenge by employing proprietary materials and an innovative structural design to suppress impedance deterioration. This ensures superior signal quality and reliable performance in demanding automotive applications.
Additionally, these inductors achieve high impedance at high frequencies, meeting the growing demands of automotive camera systems. Despite their compact size, the components can handle currents up to 480mA, making them the industry’s smallest multilayer inductors tailored for PoC applications.
Mass production of the series began in November 2024, reflecting the company’s commitment to advancing inductor technologies, including multilayer, wire-winding, and thin-film designs. These components are poised to play a pivotal role in enhancing ADAS performance, enabling safer and more efficient vehicle operations worldwide.
