    Resistor rating

    Having a little trouble finding the rating for this shorted resistor. The 5 bands are such: Black, Blue,Silver,Gold,Green

    Re: Resistor rating

    Could it be green,blue,silver ? that would be 0.56 ohm, your resistor is fine its not shorted its just a low value

    0.6 ohm 5% temp coef 20

        Black = 0
        Blue = 6
        Silver = X0.01 or 10% tolerance (it has no numeric value)
        gold = X0.1 or 5% tolerance (no numeric value)
        green = 5 or .5% tolerance or if the 5th band 20 tep coef.

        Are you sure its a resistor and not an inductor (coil)?

          Ok, then it must be ok and not shorted like I thought.
          Thanks!

            Re: Resistor rating

            FYI: resistor usually goes open circuit, not shorted out especially the MOX type like you have. That resistor is connected the Source pin of the MOSFET?
            What are you fixing any way?

              Re: Resistor rating

              I hope this doesn't turn into a "what color is that dress" thread. Fortunately only EE's and technicians would be interested.

              There are a lot of rules on resistor bands to help against reading wrong.

              1. The first band is never black. The guides may hint at black possibly could be first, but it is never black => if it is black, this is the last band instead of first.
              2. Second band is never metallic.
              3. If third band is metallic, that's a multiplier and not a significant figure

              Inductor significands should not be metallic either!

              So this should be:
              green (yeah it looks like very poor green)-blue-silver-gold-green

              56 as significand is a "E12 standard value" for 10% or better resistors so this is another check.

              Despite this all I can get from the bands is that it's a 0.56 ohms 5% Flameproof and I don't know what the green is (probably temp coefficient)


              So I have more resistors, what are the values of these resistors?

              My guesses (select to see them...):

              0.1Ω 5% 1W CC (blue band = ?)
              1.0Ω 5% 1W CC
              0.12Ω 5% 1W FP
              2.7Ω 5% 1W FP
              4.7Ω 5% 1W CC

              0.47Ω 5% ¼W FP (white band = ?)
              0.2Ω 5% 1W FP (note: first significand might be brown...)
              3.3Ω 10% ½W CC
              5.6Ω 5% ½W FP
              1.5Ω 5% ½W ?FP


              CC=carbon composite (catch on fire or smoke when overloaded)
              FP=flameproof (opens up without fire)

                Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!
                by reessi
                Hello:

                I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


                I started on the ACER:

                Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
                All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

                I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

                A Shorted wirewound resistor?
                by socketa
                This resistor is from an ATX APFC PSU that connects bridge rectifier negative to primary capacitor negative
                I think that it's a current sensing resistor for the APFC
                Is it correct that it's color code indicates that it should be 0.47 ohms?
                I measured it to be around 0.08 oms
                The PSU blew up (visible arc flash) after problems with a powerstrip, but i got it working now after replacing the 10A fuse, rectifier, etc and removing/shorting the APFC diode locations and using a jumper in place of this PFC current sensing resistor
                I don't think that APFC likes being connected...

                Dell 2209WA - power supply - Fusible Resistor replacement
                by jinu_j
                Hi

                I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

                1. FR950 - blown fusible resistor - 0.2 Ohm 1W
                2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
                3. R835 - Blown Resistor - 20KOhm SMD resistor

                Need help to replace burned resistor in 350w atx psu
                by mikey5791
                Hi to all forum members,

                Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
                The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

                Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
                Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

                Can a resistor lose resistance after hot air?
                by MidnightRoller
                I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.

                I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors...
