Reading a color-coded tantalum capacitor?
« on: June 29, 2015, 05:42:37 pm »
Whoohoo! I finally have a question after much lurking here.

I am a vintage computer collector and fix items here and there as well as replace capacitors both because of a need to replace a bad one and for preventative maintenance (to avoid corrosion of leaky caps). Yesterday, I ran into a color-coded tantalum capacitor that has me confused on how to read it.

I have an old PerSci floppy drive with dual controller boards from the early 80's.  I put it into an old S-100 system and shortly after power up, the "magic smoke" was released from one of these caps.  I immediately powered down.  Below is a picture of what's left in the area marked C12 (or C13).

There are other caps that are similar so I've included a picture of another cap with the same markings.  After looking at http://www.csgnetwork.com/capcctantcalc.html, I believe it to be 10 uF @ 16volts if I read it correctly but the little picture says 1Uf @ 16v so I'm a little unsure if the blue line denoting positive is a multiplier or not.  Does someone know how to read it?

Thanks in advance.
