I have been trying to identify this resistor so I can order replacements as several are bad in my device. It’s fairly large. 11mm x 5mm? This is an estimate in reference to the nano2 smd 7a fuse in the socket near by and several other components on board. I have provided a picture with the component circled in red. Any help is greatly appreciated. 50mOhmF SMD resistor. .05ohm or 50M ohm? Any part numbers provided for replacement much appreciated. Most of the ones I find are much too small 6mm L x 3mm W. Thanks!!!enter image description here

  • \$\begingroup\$ Well, there are actually two of them melted/bulging in circuit. So.. I suppose it’s an assumption, but also those two stations do not work. So, even if they were to test good, I’d still like to replace them since they are leaking black plastic onto other components. \$\endgroup\$ – The Beef Dec 21 '19 at 10:32
  • \$\begingroup\$ I also used my MM to poke around and found 2 of the nano2-SMD 7A fuses were bad, with no continuity. \$\endgroup\$ – The Beef Dec 21 '19 at 10:39

    \$\begingroup\$ That sure looks burned through. I'd be worried that something else got damaged. \$\endgroup\$ – JRE Dec 21 '19 at 10:51

    \$\begingroup\$ My bets is that that’s a current sense resistor and them failing is just a symptom of something else and bigger failing. \$\endgroup\$ – winny Dec 21 '19 at 13:55

It seems that the type is SLN5TTED50L0F from KOA Speer (http://www.koaspeer.com/slw07-slw1-sln3-sln5/). The F stands for 1% tolerance.
