    Re: Resistor

    42E = 2m67
    maybe

    because the last digit is not listed on my data - maybe the tolerance.

    lookup E96 coding

      I know the letter position marks decimal point EG 42.2 just not sure of ohm kohm or mohm

          From one i did before i think they used that type of markings in italy and such

            Re: Resistor

            Resistors are identified on a circuit with numbers and letters to show the exact value of resistance - such as 1k 2k2 4M7
            The letter W (omega - a Greek symbol) is used to identify the word "Ohm."
            but this symbol is not available on some word-processors, so the letter "R" is used. The letter "E" is also sometimes used and both mean "Ohms."
            A one-ohm resistor is written "1R" or "1E." It can also be written "1R0" or "1E0."
            A resistor of one-tenth of an ohm is written "0R1" or "0E1." The letter takes the place of the decimal point.
            10 ohms = 10R
            100 ohms = 100R
            1,000 ohms = 1k (k= kilo = one thousand)
            10,000 ohms = 10k
            100,000 ohms = 100k
            1,000,000 ohms = 1M (M = MEG = one million)

              Re: Resistor

              SO i guess it is a 42.2 ohm

                Re: Resistor

                your playing a dangerous game making those assumptions.
                i hope your right!

                are there other resistors on your circuit with a letter code you could meter?

                    Re: Resistor

                    The last number is the power of 10. That would make it a 4.2 X 10^2 or 420 ohm resistor.

                        E for Exponential notation. Like the "E" key on a TI calculator.

                                  All these time I thought we are talking about SMD resistor with '42E2' marking on the top, it is through hole resistor with color band code.
                                  So where did you get the '42E2' from?
                                  Pictures are always important.

                                    That is the value marked in the service manual schematic 42E2 rest are marked regular 10K and such.

                                      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...

                                      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?

                                      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...
