What value (pF/uF) this capacitor?

It's blue, it has a brown blob on the side, a small grey and a small brown spot on the top.
I've not been able to find a reference to this colour code, does anyone know how to read it?

Thanks. but how does the code work? Blue - 6, Grey - 8, multipler (brown) - 1, I can get, I don't see the priorities - and why there's two brown marks? L
Its a black art I'm afraid. It depends on relative spot sizes AFAIR. The second brown mark is a tolerance. I'm trying to find you a colour chart somewhere with these damned things on it. You can see why putting little numbers on the buggers is more popular now can't you !!

Don't bother trying to find a chart, I've already wasted my time on that.


Shoot, I had a chart a few months back too......it is very frustrating, really. Makes one want to buy a capacitance meter just to avoid the hassle.... THIS one includes all but the disc type you have on hand

Here is a Calculator that may help some.

Thanks - I did look, but so far only Steve seems to know this particular spot-code... L
Yeah, there were a couple of odd ones that different companies used; some for only short periods of time. I hated the lack of standardization with caps. (I also have some 5 band resistors that bug the bleep out of me too ;-)

I'd quite like a decent system: resistors are easy to test, but they habve an easy code. Caps' aren't and they don't (always) L
Yes, it really is sad about caps. Those resisters I mentioned are fractions of an ohm ratings.....*sigh* talk about precision resistance
