[QUOTE="Holes Flow, post: 1852177, member: 404472"] One example: I'm fixing an 820-00281-A/A1707, and a slew of cold solder joints has me replacing hundreds of SMCs. The 4 pin 'current sensing' resistors like R5750 are: 0306-SHORT MF 1/3W 1% 0.005 ...used to sense current in lots of places with INA210s, and I think INA214s, among others. My only problem is that I can't locate exact part numbers for these guys. they secure to LB with 2 'normal' pads, and 2 elongated ones: [ATTACH=FULL]31682[/ATTACH] Same problem with the crystals, as I can't match the schematic specs to digikey lookups, but that is another post... :) [/QUOTE]
