Additional Information
Designed to withstand operating temperatures from -40°C to +125°C, these inductors are suitable for a wide range of demanding electronic applications. For detailed specifications and usage guidelines, please refer to the datasheet.
Note: The datasheet was not processed; please search the internet for the part number for more details.
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.
