I have an Avalon Nano 3 bitcoin miner, however it has a 4R7 choke that broke after a week of use, I can’t find anywhere that sells replacement chokes. Do you have any suggestions? Thanks a lot

Hello @chuyenxomlangtoi

From the images you have provided, that fixed inductor is a 4.7uH metal composite inductor from Würth Elektronik and I have provided a link below to those inductors. If you are able to find what size your inductor is that will narrow down the list to the inductor will match the one out of your Canaan Avalon Nano 3

My inductor size is: 4x4x3 mm. Which one should I choose?(height is 3mm). Thanks

Hello @chuyenxomlangtoi

Based on those measurements it would be part number 74438357047

All are 4.7 uH, which is the same as mine. But the Amp and DCR are different, which one should I choose for the correct one besides the size?
