TDK Expands MLJ1005-G Series of Multilayer Inductors for Automotive PoC Circuits
The MLJ1005-G series, measuring just 1.0 x 0.5 x 0.5 mm, is the smallest multilayer inductor available for PoC circuits. Despite its compact size, the series delivers superior performance, supporting up to 480 mA of current and ensuring high-frequency capabilities essential for modern automotive systems.
Addressing the Needs of ADAS
Advanced Driver Assistance Systems (ADAS) have become a cornerstone of modern vehicle safety, leveraging automotive cameras and sensors to monitor the surrounding environment. These systems often rely on multiple cameras installed at strategic points—front, rear, and sides—to provide real-time imagery for secure driving.
Traditionally, automotive cameras required separate wiring for power and signal transmission: one line connected to the vehicle’s battery and another to the electronic control unit (ECU). However, PoC technology allows both power and data to travel through a single coaxial cable. This integration not only simplifies the wiring architecture but also reduces vehicle weight, which contributes to improved fuel efficiency and lower carbon emissions—a critical step toward more sustainable transportation.
The Role of the MLJ1005-G Series
In PoC systems, filters comprising multiple inductors are essential to separate power from data signals before processing. The MLJ1005-G series, developed with TDK’s proprietary materials and structural design innovations, excels in this role by minimizing impedance deterioration, ensuring reliable and high-quality signal filtration.
The inductors are also optimized for high-frequency performance to accommodate the increasing data transmission speeds in PoC applications. These features make the MLJ1005-G series an ideal choice for automotive PoC circuits, particularly for ADAS cameras that demand both miniaturization and high efficiency.
