I’m trying to identify this resistor, any help would be greatly appreciated.
It seems like this may be an NKN resistor (that’s what the last black band means from what i could find), possibly 0.05 ohms…
The only one with those values I’m able to find is this part number which has been discontinued: NKN400JT-73-0R05
But issue with that part is, it’s way to large.
The one I have matches the size of NKN100 series which is much smaller (5mm x 11.5mm)
Really hoping someone could point me in the right direction here
Hi,
Well I think I may have found an answer. I see Yageo has a similar option that uses an extra black band on the end for a series designator, and this should only be a 4-band resistor. The 4 band looks to be a .05ohm and 5% so I have a link below to some stocking options. The size should be able to be close or matched off the link of options.
black, green, gray, gold and black resistor last black is a series designator most likely, page 13 of datasheet
Possible options that match
Thank you
Ryan
Greatly appreciate your quick reply and confirming that I am reading the resistor value correctly (0.05ohm)
I’m not an expert as you can tell, but know barely enough to get me in trouble…
Considering that the original resistor appears to be of NKN Series by Yageo, which basically means it’s a non-inductive type.
How much trouble would I be if I replaced it with a standard resistor?
Taking a look at the link you provided, I didn’t see any of them labeled as “non-inductive”.
The application seems to be part of a sensing circuit, as much as I could tell at least.
Just to provide some context, it is going into the RC Car battery charger that can charge multiple types of batteries. I have several different chargers (different brands and types) and they all seem to use that same resistor. I have also seen that same identical resistor used in electric scooter chargers. So I would think that it has to be somewhat popular, but I couldn’t find that exact one anywhere…
Switching resistor types may cause issues with the circuit, there is a reason why the manufacturer used a non-inductive resistor and that is what I would replace it with. Take a look at DigiKey part 696-1731-ND as a possible alternative, this is a 1 watt , 0.05ohm, 1%, non-inductive resistor.
Thank you very much for the advise, you guys are great. I’ll be ordering several just in case.
