Wire Wound Resistor Specification

By on May 2, 2013
wirewound resistor

Wire wound resistors are different from the carbon film and the metal oxide film resistors because the values are printed on its body. The values are easy to read as compare to the color bands type. So in the picture, let us guess what is the specification of the resistor. Please leave your comment below-thanks.

      Hi Waleed,
      5 watt is correct but the value is incorrect.

      Hi Beh,

      5 Watt is correct but not the value. Please try again

    there is K after the number so, if not 15K then it is 1.5K.

      HI Daniel,

      0.15k ohm means 150 ohm nope not the answer.

    It is 5W .15 ohm and 10% tolerance the k is 10% tolerance I see that threw many off...

    I remember my basic tolerance markings a weird way,
    I remember MKJHGF and I pronounce it as a two syllable word "MaKuJ-HaGuF", then I can remember the MKJHGF part easily and go from there as these correspond with the 20%,10%,5%,3%,2% and 1% tolerances.

          Hi Jim,
          Normal meter can't really test out the value. Use Blue ESR meter that can measure down to 0.01 Ohm.

          Hi Jestine Itried testing the 5w R15K risistor on my digital multimeter with it set on 15k and it showed all zeros so i set my multimeter to 200 ohms and it showed 00.3 have i done this right and is this a bad risistor and what setting should my multimeter be set on

            Hi Jim,

            The value is .15 Ohm and not 15 K ohm. So you need a low ohm resistor tester such as Blue ESR meter to check on the value. K is the tolerance.

      Hi All,

      To those who have answered 0.15 ohm 10% tolerance and 5 watt resistor-this is the answer.

      Thanks for trying.

      Hi beh,

      Correct answer and the resistor is use to limit inrush current.

    hi Jestine, remember me..i bought blue ring tester long time ago..been looking for answers for these type of resistor, and i found this thread

    so basically

    5W35ΩK is totally different from 5WR33K, i just bought 35Ω wirewound resistor yesterday, thinking the one im replacing is 33Ω, which is .33Ω

    by the way..how do i know if it is good or bad..

    thank you very much..,God bless

      Hi Ryan,

      Yes it is a .33 Ohm and oyou need a low ohm meter to check the value. You can use a digital meter that can measure from 0.01 ohm onward or the blue esr meter.
