# What is the value of this 5-band resistor

The colors are black, light green, green, red and silver (looks more like gray). I am not sure which side to start reading the values from. Both ends seem to be symmetrical.

Moreover, I have never seen light green on any color code charts. i am thinking that the manufacturer might have intended this to be yellow (but I am not sure).

I know the basic color code and have also worked with simple electronic circuits, but, this resistor got me really confused. I looked up various sites to do some research, but ended up with more questions than answers.

• My guess is either, 4.5 kohms x 0.05% (if second color is yellow) or, 5.5 kohms x 0.05% (if second color is green). – BlueKryptonite Aug 27 '19 at 23:43
• I suspect that you should be reading it the other way, since grey-red translates to 82, which is a standard value in the resistor E12 series. Can't help you with the rest though. – brhans Aug 27 '19 at 23:48
• Maybe 8.25 M$\Omega$ (gray-red-green-yellow), a standard value in E48, E96 and E192 series. Can't explain the last band, though... looks black but that doesn't make sense... could it be dark brown meaning 1% tolerance (E96), maybe? – Enric Blanco Aug 28 '19 at 0:06
• May be a bleed resistor (seems to be going to ground), and it possibly crosses a high-voltage barrier indicated by the broad white silkscreen. If so, its resistance may be high, as Enric Blanco suggests. – glen_geek Aug 28 '19 at 0:45
• Measure it. It'll be horribly inaccurate in circuit, but it'll get you into the ballpark -- especially if it's an inductor. – TimWescott Aug 28 '19 at 0:45

Allowing for distorted colors, I read it as 825 with 4 zeros (sickly yellow), 1 percent (overly dark brown), carbon film (light brownish body); or 8.25M, a standard value. The questionable part is that carbon resistors of this value have such a large tempco that one percent will only be met over a ten degree range (or less).

• I would also go for that as black-yellow is uncommon but gray-red is standard E12. But then 8.25M is also rare. – Oldfart Aug 28 '19 at 5:28

I agree with @brhans in the comments on the direction of reading. (Grey, Red, Green, Gold?) and I believe the black band is to indicate that it is a wirewound resistor.

You can see similar markings using the 5th black band in the datasheet for these resistors by Yageo

• The dark band on the end is black and this 1/2 watt resistor is in the part of the circuit that handles 120 volts. – BlueKryptonite Aug 28 '19 at 3:25
• Yes I see, please read the comments of brahns, Enric Blanco & Glen Geek. I agree with them. Are you able to lift one side and use a meter to read it? Since the resistor looks ok, you are in the best position to answer this question... – narkeleptk Aug 28 '19 at 3:31
• Although my multimeter was showing an open circuit for this resistor, it is only because the maximum resistance measurable by the multimeter is 2MOhms. Later on, I figured that one of the reasons for the circuit board to not function correctly is a fusable 1.8 ohm ceramic resistor (RGDU5M-5E), which is showing open circuit. The new problem is that this exact resistor is kind of hard to find. Also, I might have other failed components that caused the fuse to blow in the first place. Thanks again to all, for educating me about the 5-band resistor. That was new information for me. Thanks. – BlueKryptonite Aug 29 '19 at 2:54

There is no light green in resistor bands. 0-Blk 1-Brn 2-Red 3-Org 4-Yel 5-Grn 6-Blu 7-Vio 8-Gry 9-Wht It appears that resistor is Gry, Red, Grn 8,200,000 Ohms (8.2 Meg).
