The inductor is made for cars. It sends power and data through a single cable, replaces multiple components, saves space, and enhances ADAS functionality.
TDK Corporation has released the ADL8030VA, a compact inductor specifically developed for power-over-coaxial (PoC) applications in automotive electronics. It offers high impedance across a wide frequency range, enabling efficient filtering in PoC systems. The inductor is also suitable for use as a wideband T-bias inductor, supporting both power and signal transmission over a single cable.
The ADL8030VA is compact, measuring just 7.8 x 2.7 x 2.7 mm, and is available with inductance values from 10 µH to 100 µH. It supports currents up to 0.82 A and operates across a wide temperature range from -55 °C to +155 °C. Models with inductance values of up to 22 µH feature a DC resistance of below 0.5 Ω, helping to reduce power loss. The device is constructed with a ferrite core, welded enamel copper wire, and flame-retardant moulding and meets AEC-Q200 qualification standards.
By combining high impedance and wideband performance, the ADL8030VA replaces multiple inductors in traditional PoC filter designs with a single component. This simplifies the circuit, saves board space, and lowers the overall component count. Its low DC resistance also helps to improve energy efficiency.
Some of the key features of the ADL8030VA include:
- Only one component for PoC filtering
- High impedance over a wide frequency range
- High mechanical stability
- Qualified according to AEC-Q200
- Suitable for AOI (automatic optical inspection)
In advanced driver-assistance systems (ADAS), where space is limited, and reliability is crucial, the ADL8030VA helps streamline power and data transmission over a single coaxial cable. As a result, it supports more compact, cost-effective, and robust automotive designs, contributing to the development of safer and more connected vehicles.
