Cap labeled 100 16F, is 16F the voltage?

Likely 100 uF 16V, and the F means something else. Measure one!

The capacitance is easy, my concern is the voltage rating of the capacitor.

Well can you measure what voltage is across the cap when the circuit is turned on?

No, I'm salvaging an smd cap of of a used junk computer mother board for a friend doing a repair. Mikek

I believe 16 is the voltage, F is for lead free. Could be wrong, I really hate these cryptic codes on SMD components, if they even bother to put a value on. I need a freakin crib sheet for SMD resistors with the EIA-96 codings. JC

Everyone needs a crib sheet for those and smd transistors, regulators fets. Somebody tell Winfield that needs to be in his book! Mikek

Why, when you write "mesure one", I read "blow one up"?

Best regards, Piotr

You can creep up on the voltage across an electrolytic and note the leakage current, to estimate the voltage rating. That (unfortunately) doesn't require exploding anything. I have seen polymer aluminum caps that died suddenly, around 1.5x rated voltage, with no current increase as a warning.

Can I borrow your car?

(Awaiting a measured response to that one.) ;)

It could be an ex-Fiat!

Even easier. Motherboards don't have anywhere near 100V on them.

Samwha RC series uses the F suffix, after the voltage, to identify itself.

I met the my friend for breakfast he showed my the RC controller board he was repairing. I'm not sure if he can fit the 22uf cap in the position where it needs to go. The cap I have is 0.2" in diameter. I didn't get to see the original, so I don't know the style. Oh well, I tried, he can order it.
