    Who can help to tell the resistor value please?

    It looks 01.

    see the pic yellow circle below.
    Thanks

        You might have better luck posting the board number or model number, What is it's resistance when checked with a meter?
        It could be a D01R3721F-GP-U

          That looks to be Source resistor for the MOSFET PU4402 which is connected in series with MOSFET PU4201 as half-bridge set up. I expect that resistor to be <1 Ohm.
          Why do you believe that resistor is bad?
          What is this board for?

            Thanks

            Its a 10 milli ohms resistor

              Looks like a laptop?
              Current sense resistor for AC or battery power circuit it looks like.

              What is the problem with the laptop?

                Hallo
                i have a Yoga L380 LKL-1 Mainboard
                there the PR4402 is only 0,6 Ohm instead the 1,0 Ohm that results in Slow charge and Fault messages regarding the charger

                According Schem its a D01R3721F-GP-U

                because you know that resistor .... do you know where i can get it ?
                Prefer Europe but i can order world wide

                Thank you

                Thomas

                  Sorry all posted Values are wrong

                  Marking R010
                  acc calculator it should be a 0,01 Ohm

                  With this low resistance value, the measurement cable must also be taken into account.
                  Unfortunately, I don't have a milliohm meter at the moment and all other measuring devices are too imprecise.
                  Best way is to change it to be shure

                    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...

                    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

                    Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
                    by chth96
                    I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
                    Since then, This AC/DC adaptor have been out of order.
                    But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
                    After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
                    Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
                    And Is there any possibility that it will suddenly explode as well as to be out...
