The Watering Hole

Howie (or anyone else that might know),

I bough a couple of .002uf ceramic capitors today and  a couple of 100k resistors that I plan to use as the "treble bleed" on the volume pots of my guitar.  So far so good.

However, in the electronics shop I only had my standard reading glasses with me so I was relying on the guy in the shop to give me the correct capacitors.

Now at home, I put my higher powered glasses on and the capacitors do not say .002 on them, instead they say 222k

Now, I'm assuming that this is just the same value being expressed in thousands instead of microfarads (uf) and I was wondering if you know if my assumption is correct, or have I got the wrong capacitors?

thanks in advance

Jon

For fun I looked this up.  Here's a website with Capacitor information: http://www.uoguelph.ca/~antoon/gadgets/caps/caps.html

"k" apparently stands for pf (picofarad) so 222k should actually be equal to .00222uf, no?  :)

aha, that's good then as that's the value I was hoping, .002 uf


Actually is that right, as that article says that a pf is one millionth of a microfarad and that a microfarad is one millionth of a farad? So where does the k come from (didn't see it in that article)

Just double check my assumption!

Most of my electronics background consists of putting resistors I stole from shop into wall sockets so I could hit the switch and hear them go *BANG!*

:D

I just found this chart, so it would seem that 222k is the code for a .002uf capacitor

I finally get a chance to show off my vast knowledge.... and I'm on vacation camping.   ;D

I answered Jon's e-mail before I saw this thread, but I do like that chart.  Another copy and paste reference.  (I'm no Dar. He has all this in memory, stored at every level... and probably since he was 12  ;))

Yes, I can confirm Howie did indeed answer my private email with a very good answer. Isn't it interesting that we DO know whom to ask certain questions in this forum.

thanks Howie
