Open Circuit Inductance Test Parameters: 100 kHz, 0.25 V rms, 0.0 Adc.
RMS current for approximately 40°C temperature rise without core loss. It is recommended that the temperature of the part not exceed +125°C.
Peak current for approximately 30% roll-off at +20°C.
DCR limits are specified at +20°C.
Applied Volt-μsec: 100 kHz necessary to generate a core loss equal to 10% of total losses for 40°C temperature rise.

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.
