    Blown Capacitor Identification

    Its a long shot but a capacitor blew on my hand mixer:

    I cannot make out the markings but wondered if anyone could help with the identification:



    Thank you

    What you have there is something wrapped in heatshrink (a tube made of thermo-plastic material that shrinks when there's heat applied). You'll have to get a sharp blade or something similar and carefully cut away that tube of heatshrink and then you should see the markings of the capacitor.

    It looks to me like that's actually a FUSE... the fuse is in that tube of heatshrink so that if the fuse pops, you don't get shards of glass or ceramic material everywhere.
    On the metal caps of the fuse, there should be a number (the current at which point the fuse breaks) and a digit (T for example for "time delay")

      Hi mariushm, thank you for the quick reply.

      You were quite right it was a fuse wrapped in heat shrink!

      The markings are T3 15A 250V which looks like quite a common fuse which I can now replace and repair the mixer.

      Thank you for your help.

        You may want to consider why the fuse blew?
        Any signs of other damage?

        If you replace with a glass fuse replace the shrink wrap.
        Please upload pictures using attachment function when ask for help on the repair

          Erm, I don't want to throw a spanner in the works here but I would be looking very carefully at that fuse again.

          Are you sure it is not a T3.15A 250V fuse???? Replacing a 3.15A with a 15A would clearly be a bad thing to do!

          It would be some seriously meaty hand mixer that used a 15A fuse!

            Yes, it's probably a 3.15A fuse.. after all, the product has a 600w motor, so at 240v mains, you have 600/240 = 2.5A. The T is for time delay, which is needed for the brief moment when the motor starts up and puls quite a bit more than 3A.

            Here's something that would work for you and you can probably buy it from them:

            pack of 10 , 1.64 pounds : http://cpc.farnell.com/_/cf2470ff-3-...20This%20Range
            It looks different, but it's time delay , 3.15a , 250v ... just isolated in epoxy instead of glass.

            If you want the classical look, you have those as well (but these don't come with leads, you'll have to solder leads on them and put some heatshrink on them or be inovative (example, get a plastic pen and break the tube and put the fuse inside and use some tape over the plastic) :

                I hope he hasn't gone out and bought his 15A fuse already then
