    Hi all,
    Can anyone advise on colour codes used on Fuses ?. The one I have is out
    of a Philips 29PT688 TV, ceramic M205 style (5mm x 20mm), but it doesn't
    have any ratings stamped on the caps only says 250v.
    The colour code reads [green,black,red & blue(wide line)]. I'm guessing
    this means 5,0,00 or 5amps. Does anyone know what the wide blue line means?
    Is it a fast acting or slow blow? any web links or ideas. I've tried google
    etc but can't find a reference to this particular coding scheme.

    Thanks in advance for any info.

    ** I have a 20x5 fuse here that is colour coded as well as stamped.

    The bands are orange, brown, red & wide blue.

    The stamped rating is 3.15 amps, slo-blo, 250 volt.

    It seems the number code is the same as for resistors - in mA instead of

    So using that as a basis, your fuse is a 5 amp, slo-blo, 250 volt.

    ......... Phil
