    Need help to identify and to locate a 0.33 ohms fusible resistor for power supply

    I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
    Resistor shows orange range silver gold and green lines.
    Thanks in advance

    I also need help identifying another component 85A50D 6 pin IC has a U under it. There is a picture with the voltages on a live circuit. There is diode voltage drop between ground and pin 1,2 and I think 3? I looked for it and could not find anything. It's from the same power supply as above. I really appreciate any help.

      85A50D = SC2585A

      Regarding the resistor, it is a regular current resistor, its resistance will not increase and it should be 0.33 Ohm.

        So it's not a fusible resistor, I also thought about using a regular 0.33ohms resistor but was told it has to be a fuse resistor!1
        Any word on the chip I am trying to locate?

          Yes, it's a tough case, I gave you full information on the chip (SC2585A) that you are looking for in post 3.

            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...

            Is this a fusible resistor?
            by bluto
            This is from the power supply of an LED shop light. The light went completely dead suddenly. I removed the SMPS board and it looked really good except for some bad solder joints. I touched all of them up but the light was still dead. I then found this open resistor that was between the neutral wire of the plug and the transformer. The color bands seem non-standard. Does it indicate 13 ohm, 30 ohm...? I am not sure. What should I replace this with?

            Hello everyone,

            I recently picked up a laptop that was about to be thrown away to try to repair it. I've tested quite a few things, but I don't know where to look anymore. Could you please help me?

            Brand: Asus Vivobook
            Motherboard reference: x421da, Rev 2

            Context:
            The person who gave it to me mentioned it might have been exposed to water, but they weren't sure. After opening it up, I couldn't find any signs of water damage or oxidation on the motherboard.

            The first thing I did was to connect the PC to a power supply: 19V stable and...

            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...
