Product Features
Dual winding, high power density, shielded drum core power inductors suitable for various applications including DC-DC converters, VRM in CPU and DDR power supplies, input/output filter chokes, and transformer applications (SEPIC, flyback).
Can be used as a single inductor or in coupled inductor/transformer configurations with a 1:1 turns ratio.
Available in four sizes of shielded drum core inductors.
Windings can be connected in series or parallel, providing a broad range of inductance and current ratings.
Peak current ratings up to 56A and RMS current ratings up to 17.9A.
Inductance ratings from 0.33 µH to 4.02 mH.
200 Vac isolation between windings with ferrite core material.
Operating and storage temperature range: -40°C to +125°C.
Solder reflow compliant (J-STD-020).

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.
