Trouble with identifying a resistor
(1/1)
FloridaTony:
I am having quite the time trying to identify a blown resistor for a power board. The resistor is clearly an "Orange-Orange-Silver-Gold-Green" resistor, but it seems like nowhere I try to look and identify it, even on DigiKey. It won't recognize the 3rd band as being silver. Any clues?
I have even attached a picture of the resistor in question.
WattsThat:
0.33 ohms 5% 20ppm tempco
Not sure about the power, it’s hard to estimate size. Is it being used as a current shunt? That’s what the value and tempco would imply.
FloridaTony:
I would believe so. It is a fairly chunky resistor that is before a fair sized mosfet with a heat sink on it.
FloridaTony:
After plugging that info into DigiKey, I may have found the replacement. It also seems like a 1 Watt resistor, especially from the measurements I took with the caliper.
