The 78F270J-RC is a high-quality RF inductor manufactured by BOURNS with a focus on reliable performance in RF applications. Designed with a ferrite DR core and enamelled copper wire, this leaded inductor offers precise inductance values suitable for various electronic circuits.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
