    Default Capacitor Color Code

    Can someone throw me a bone for the thread at badcaps that has the capacitor color code for manufacturers?

    I've never seen a manufacturer's color code posted. Might be there somewhere but I've never seen it.
    Register and give Galvanized the referral(please) and ask. willawake, Topcat, kc8, Big Pope, davmax, gonzo, Per Hasson, Yanz are all very sharp and helpful. You could look through the bad / good caps pic threads and note each type but that won't really work that well because the lower capacitance Teapos won't be green with a gold strip like the ones we see on a PSU's secondary. This is true of most brands I've seen.

    Some links I'll throw at you that *might* be useful.

    Damn, I thought it was bad caps I saw a chart of them at (now i wonder where the hell it was)...and I am already registered...have been for a while just couldn't find what Iwas looking for

    I've also seen them somewhere Spectre but color codes don't reflect manufacturer (although there can be mfg print), they reflect capacitative values.

    A fella on xtremesystems (Hipro) had some caps a while back that were 100000uF/75V rated

    Here's the closest I could find to understanding them in a simple way and without muddling resistor values up which many of them seem to do: How to read capacitors (less math )

    Further: For our purposes the imprint struck on the aluminum vent cap is the first indicator of brand. It can be a tri-star, a tri-star with little dashes between the legs, an X or a K.

    For the electrolytics it is easiest just to read the info and brand off the caps, in rare cases it can be difficult to find the manufacturer but if it is they are probably trash. Reading them by colour will probably just confuse as there are a lot which are the same colours. Same thing with the vents although the vents can be useful to eliminate some brands when someone is not giving very complete info.

    there are some smt silver ones which are occasionally not possible to identify, just read the values off them. then with LCD panels some ceramic ones (usually blue discs with two leads) can partially burn and there it will be necessary to use the codes to find out their values.

    i dont think it is so necessary to know how to identify all the brands, the most important thing is to identify the voltage and capacitance uf and then replace with the best low esr caps you can obtain.

    Question: Did you ever find out the primary caps in the Sunbeam Nuuo? I have one here and I'm wanting to put it in, but am I worrying too much about Fuhjyyu and unnamed brand caps on the primary / secondary?
