Introducing the Eaton Electronics Coupled Inductors with part number DRQ74-220-R. Manufactured in China, these high-performance inductors are designed for demanding electronic applications requiring reliable power management and filtering solutions.
These shielded drum core power inductors feature dual windings that can be configured as either a single inductor or in coupled inductor/transformer applications with a 1:1 turns ratio. They are suitable for use in various applications including DC-DC converters, VRM in CPU and DDR power supplies, input/output filter chokes, 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.
