Resistor colour code

[remzy]

I've been dealing with fixing and making electronic projects for a few years now but my knowlege is still not perfect. I need help about this resistor. I just haven't ever seen this colour code on them before: Black, gold, silver, red and blue
Here is a picture.

This may be an inductor, not a resistor.
Inductance 0.62µH

Or, if it really IS a resistor: 0.62 ohms. 62 is the two significant figures from blue and red bands, silver band means multiply significant figures by 0.01, gold band means 5% tolerance; ignore the black band.

If it IS an inductor, as Harald mentioned, 0.62 μH is a quite small value. You may not be able to distinguish this component from a low-valued resistor.

I'm pretty sure it's a resistor because its marked as one on the pcb.

0.62 ohms might be hard to measure with a multi-meter. You could connect it to a constant-current source and measure the voltage drop to verify the resistance. No constant current source handy? Just wire it in series with a 100 ohm resistor and connect the series pair to a constant voltage source of about five to ten volts. Measure the voltage drop across the "0.62 ohm resistor" and use the voltage divider equation to determine the resistance.

An unmistakable sign.

I would've done that but the resistor is blown from the other side. I've just took a picture of it where you can see the colours clearly. I didn't know about that method. Thank you!

colour code on them before: Black, gold, silver, red and blue

you read the colour code back to front

I've realised that later on. Thank you
