TDK intros automotive power-over-coax inductor for filtersd

TDK Corp. has launched the ADL8030VA, a high-performance inductor designed specifically for power-over-coaxial (PoC) applications.

Due to its high impedance over a wide frequency range, this component streamlines the PoC filter design by requiring only one single component instead of the conventional approach with two or more inductors. This significantly reduces complexity and cost in advanced driver-assistance systems (ADAS) and other automotive electronics, where space efficiency and reliability are critical. With the ADL8030VA, TDK is once again driving mobility transformation toward a more connected and safe future.

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). However, with PoC technology, a single coaxial cable can simultaneously carry both power and data, simplifying and reducing the wire harness.

The 7.8 x 2.7 x 2.7 mm (L x W x H) small ADL8030VA series offers inductance values from 10 µH to 100 µH with a rated current range of up to 0.82 A, ensuring robust performance from -55 °C to +155 °C across a wide frequency spectrum. Its low DC resistance of less than 0.5 Ω for the types with 22 µH or less minimizes power losses, enhancing overall energy efficiency.

Its compact design is engineered with a ferrite core, enamel copper wire welded to the terminals, and flame-retardant molding. It offers high mechanical stability, and meets AEC-Q200 qualification standards, ensuring durability under harsh automotive conditions.
