Introducing the Eaton Electronics BS series coupled inductors, part number DRQ127-821-R. Designed for high-performance electronic applications, these shielded drum core power inductors are ideal for use in DC-DC converters, VRM power supplies, and filtering solutions.
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.
