    Identify a resistor

    Hi! This is probably a dumb question but I can't really figure out the value of this resistor.
    Can anyone help?
    Thanks!

    0.47Ω non-inductive

      Re: Identify a resistor

      0.47Ω, ±5%

      One key is that the metallic bands (silver/gold) are not significant digit colors and since there are at least two significant digits, it's not the black side that goes first.

          Flame-retardant resistor type "Anti-pulse".

            Thank you for the reply.
            What does this black stripe means?

              In most cases the last black band indicates non-inductive
              If it was White, it would be Fusible
              In some cases it is Temperature Coefficient (Black= 250ppm/K)

                  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
                  4. D930 - Shorted Schottkey Diode...

                  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...

                  What resistor ohm will work better to repair this waterpik?
                  by artvandalai
                  The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y
