In-vehicle PoC inductors

By making use of suitable inductors from Murata’s extensive lineup, such as the LQW-F series developed for PoC applications such as ADAS camera interfaces, it is possible to create wide-band Bias-T circuits that employ fewer components.
The “Bias-T Inductor Selection tool” on the Murata website can help you select the best components for your Bias-T circuits.
