Introducing the Eaton HCMA1305-4R7-R automotive-grade high current power inductor, designed for demanding electronic applications requiring high current capacity and reliable performance. Manufactured by Eaton Electronics in China, this surface-mount device (SMD) is ideal for automotive and industrial electronics.
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.
