Open Circuit Inductance Test Parameters: 100 kHz, 0.25 V rms, 0.0 Adc. RMS current for an approximate temperature rise of 40°C without core loss. Peak current for approximately 30% roll-off at +20°C. DCR limits are specified at +20°C. The Volt-μsec value indicates the voltage-time product necessary to generate a core loss of 10% at 40°C temperature rise.
For more detailed specifications and application information, please refer to the datasheet.
Note: 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.
