    Some help identifiying a resistor

    Had csi 825 hot air station go bad.
    Getting bad readings on this resistor
    Could do with some help identiying the rating

    So its

    Brown Black Gold GOld

    1ohm resistor

    Its massive through
    3cm wide

    Its been used as a fuse resistor

    Any recommendations on where to source repalcement

      1ohm 5%
      wattage will depend on size.
      it's a flameproof type btw.

        http://www.maplin.co.uk/p/wirewound-...m-resistor-h1r

        will that replace it ?

        Its 24mm Length

        8mm width

          If it's used as a fuse resistor you may have a short somewhere else too.

          Source from wherever you like. eBay, Farnell, Digikey, etc.

          That one you linked to should be fine, but it's not going to fail like a fuse in the same way as the old one did on overload. You may wish to add a real fuse in series as well.

            The element blew out
            And took the fuse resistor with it..
            A glass fuse ?

            thanks for the info guys

              dont use wire-wound - they are inductive.

              use metal film type

                Glass is OK, ceramic is better.

                Would the inductance of a wire-wound resistor really matter here, given that the heating element is probably coiled and has its own parasitic inductance anyway?
