Open Circuit Inductance Test Parameters: 100 kHz, 0.25 V rms, 0.0 Adc.
RMS current for an approximate DT of 40 °C without core loss. It is recommended that the temperature of the part not exceed +125 °C.
Peak current for approximate 30% roll off at +20 °C.
DCR limits @ +20 °C.
Applied Volt-Time product (V-μs): 100 kHz necessary to generate a core loss equal to 10% of the total losses for 40 °C temperature rise.
For detailed specifications, 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.
