Resistor value - color coding

[Askic]

Hello electronics expert,

can you please tell me what is supposed value of this resistor?

I'm really having a hard time figuring this out, because black lines on first place means 0 and gold lines are multipliers 0.1.

It seems like colored rings are: black gold gold black orange.

Based on the chart below, I'm guessing .3 ohm, 250 ppm tempco.

In this case I believe the last black band indicates non-inductive

Thank you for the reply, but how did you figure this out?

To me, according to the same table
First band is black = 0
Second is gold = N/A
Third is gold = N/A
Fourth is black, multiplier 1 (10^0)

???


According to the second table from R_J:

first band black = 0
second band gold = N/A
third band gold = 0.1 multiplier
fourth black = tolerance

The first band on your resistor is ORANGE

Hello R_J

Thank you for the reply. Orange as first is the only way to have 3 in its value, when I look that way, Orange Black Gold Gold Black (3 0 N/A 0.1 250 ppm/K)

So, this seems as 3 ohm and not 0.3 (30 x 0.1).
Unfortunately, this color scheme is not obvious to me.

Perhaps key observation: if you have a metallic band and it seems to be first or second band... need to flip the resistor around and try again!
