Hello

I have a pair of RM3300SAT Speakers, which have a blown capacitor. I was wondering if someone could tell me what te replacement capacitor would be, by looking at the picture.

Thanks
Mike

    From that pic - not without a schematic. I would say it is an electrolytic though.

    The value of your electrolytic cap is 5.8 microfarad, 50 volt, +/- 5% tolerance. I'd recommend you replace it with another electrolytic as the film/foil type caps would be a waste in those speakers. Do you know why it popped?

    not sure i got these speakers from my friend, and he said that they have never worked. I could buy the capacitor online somewhere i would presume.

    If the speakers where not pushed, then my guess the cap is old where it leaked at little (internal resistance) this caused some heat internal which caused it to burst.

    Disneys right excessive heat kills caps on top of old age and being cheap construction to start with. I had problems with the capacitors in my 3000gt vr4 caps got hot started leaking and then pop goes the engine computer DOh! 400.00 dollars later.

    I would check at Radio Shack first. A little pricey but it is instant and no shipping charges or minimum orders.

    Take note, from your pictures the cap has a +/- 5% tolerance, not 20%. I seriously doubt RS has one, but any real electronics store will. Probably cost you about $0.50.

    I don't think so but is a crossover cap polarized? That cap looks like a typical dc cap.

    From those close up pictures, I'm not so sure that cap has popped. It looks like they have hot glued all the caps down to the board, so what looks like gel leaking is really glue. Is that substance at the base of the cap feel like hair gel or is it hard like dried glue from a glue gun?

    They have them glued to the pcb board
