TDK Corporation introduced the ADL8030VA, an inductor designed for power-over-coaxial (PoC) applications in automotive electronics, including advanced driver-assistance systems (ADAS). The component uses a single inductor for PoC filtering, replacing the conventional use of two or more inductors, which reduces complexity and cost in system design.
In PoC technology, a single coaxial cable transmits both power and data, eliminating the need for separate power and signal lines typically required for ADAS sensors, such as automotive cameras, connected to the battery and electronic control unit (ECU). The ADL8030VA, measuring 7.8 x 2.7 x 2.7 mm, offers inductance values from 10 µH to 100 µH and a rated current of up to 0.82 A. It operates across a temperature range of -55 °C to +155 °C and maintains high impedance over a wide frequency spectrum.
The inductor features low DC resistance of less than 0.5 Ω for types with 22 µH or less, reducing power losses. Its design includes a ferrite core, enamel copper wire welded to terminals, and flame-retardant molding, providing high mechanical stability. The ADL8030VA meets AEC-Q200 qualification standards for durability in automotive conditions and is suitable for automatic optical inspection (AOI).
