content: HiI have a strange resistor.That looks like normal resistor.But my multimeter devices couldn't read the value.so i tryed to solve the problem with color code chart.But no hope.Can you guys please give me the value of this resistor?white / gold yellow / black / white / red93x1 ? 50ppmorred /white / black / gold yellow / white29x1 %5 ?Sorry i really don't know which side we should start to read.You can see it in picture.Thank you very much.

content: 29 Ohms +/-5% What about the white color at the end?Ok thanks.

content: To be sure, take a resistor of minimal value that your multimrter will measure. Then put the unknown one in series.

content: I vote for 24 ohm 5% (with a faded or a yellow second band that looks more like white than yellow).Either that or you have a very rare 29 ohm 5% resistor.Does your meter show very high or very low resistance? It could be a bad resistor.

content: Maybe 29 ohm 5% fusible resistor?If it's a fusible resistor it would be more likely to be an open circuit.

content: If it's a DC short then that would indicate it's an inductor... it would be rare for a resistor to fail short.

content: Green so could be a dipped ceramic capacitor. Try measuring the capacitance as well, or if you have a few cut one in half to be sure.

content: I have a Mastech MS8229 multimeter and Fluke 45 bench multimeter.Mastech measures400 ohm up to 40Mohms.I also measured with Fluke 45 (300 ohms up to 300Mohms) L.O as well.

content: Quote from: Savetheday on September 13, 2015, 10:46:04 amThose are the "full scale" ranges of your meters. They actually measure 0 - 40M/300M ohms.The high resistance means that you either have a capacitor or open resistor. Which ever it is, it appears to have an uncommon value.
