I have a capacitor which has the mark on its body "470 k 50v." Does 470 mean it is a 470 pf or a 47 pf capacitor? Both are possible? God bless!

Does 470 means it is a 470 pf capacitor or 47 pf?

** Though very rare - I have a bag full of various value Silver Mica caps that use the "0" to show there are no naughts!!.
Eg: 330J = 33 pF, 5%.
Mind numbingly stupid.
Only a DMM with capacitance range will settle it.

Not really, just look at a 10 ohm +/-5% carbon film resistor.

** How mind numbingly * STUPID * of John Fields.The cap example is appallingly ambiguous.
His resistor example is not.

It reads the same as the resistor color code; it's expressed in numbers rather than color bands. The first digit is 4, the second digit is 7, and it's followed by zero zeros (or you could say "times ten to the zeroth power", which is 1), so it's 47 pf. The K indicates either the temperature coefficient or the dielectric type - I'd have to look that up.
Just for reference, a 470 pf cap would be marked "471", and so on.
The "50V" should be fairly self-explanatory. :-)

** But with a monstrous ambiguity that is not there with resistors. ** So if you see a ceramic cap marked " 470 K" - what is it's value ?
As usual - you utterly missed the point.

WOW. You got another one right!
That's two in one week!
Actually K is 10% tolerance.

How nice of you to contribute.
Well, like the time when I was losing miserably at poker, and quoted my Mom: "Unlucky in cards, lucky in love", some guy said, "Yeah, and one out of two ain't bad!" ;-)
Thanks! Rich
It's OK. I've been ignoring Phalluson for years.
Cheers! Rich
