Default Tantalum caps markings

Sorting a bag of old caps I had laying around, I'm stuck with a few capacitors I can identify.

They are through hole tantalum caps with "336F" or "33GF" (difficult to say).

Any idea ?

I would suspect it 336F which means 33 Uf
or 33 and 6 zero's also 33 Uf. The F usally means 1%

Hi, Kemet tantalum capacitors have a nice pdf data sheet w/ drawings that you might find informative.

Scroll down towards the bottom and look for 'F3100_TaDipRad.PDF' for download...

Value is correct, but the suffix letter stands for the working voltage, not the tolerance. I do not know which value is F however.

Maybe F means 35Vdc

They are painted with different colors?

That's what I tend to think too but I couldn't find any datasheet which uses "F" as a voltage rating. Well, if I can't find the voltage rating, i'll use it with 5V or 3.3V regs.

The marking is all black on the typical orange/yellow body. It's like that

336F *
