Discover the high-performance coupled inductors from Eaton Electronics, designed for demanding electronic applications. These shielded drum core power inductors are ideal for use in DC-DC converters, VRM power supplies, input/output filters, and transformer applications such as SEPIC and flyback.
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.
