TDK Corp. has launched the ADL8030VA, a high-performance automotive inductor for power-over-coaxial (PoC) applications. The PoC inductor reduces design complexity and cost in advanced driver-assistance systems (ADAS) and other automotive electronics, where space and reliability are critical.

The ADL8030VA inductor streamlines the PoC filter design by requiring only one component instead of the conventional approach with two or more inductors, thanks to its high impedance over a wide frequency range, TDK said.
“In standard configurations, ADAS sensors like automotive cameras require two separate lines: one power line connected to the battery and a signal line connected to the electronic control unit (ECU),” TDK said. “However, with PoC technology, a single coaxial cable can simultaneously carry both power and data, simplifying and reducing the wire harness.”
Key specifications of the ADL8030VA series include inductance values from 10 µH to 100 µH with a rated current range of up to 0.82 A, and an operating temperature range of -55°C to 155°C across a wide frequency spectrum. The PoC inductors also offer low DC resistance of less than 0.5 Ω for the parts with 22 µH or less, which minimizes power losses, enhancing overall energy efficiency.
The automotive inductors, housed in a 7.8 × 2.7 × 2.7 mm package, feature a ferrite core, enamel copper wire welded to the terminals, and flame-retardant molding. They offer high mechanical stability and meet AEC-Q200 qualification standards, ensuring durability in harsh automotive conditions.
