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. 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-μs (V-μs) across the inductor represents the voltage-time product necessary to generate a core loss equal to 10% of the total losses for a 40°C temperature rise.
Application Areas
Desktop and server power supplies
DVD and media players
Portable and handheld devices
LCD panels
DC-DC converters including buck, boost, forward, and resonant types
Noise filtering and filter chokes

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.
