Title: Help finding a replacement part Post by: proten on October 03, 2013, 10:22:53 PM I've replaced the BNC connector on my O scope and
I broke a small ceramic capacitor. It is marked (0.001 P), is this the same as a 0.001 uf ? The Tektronix manual says that it is a adjust as needed for calibration so no help there.

Title: Re: Help finding a replacement part Post by: proten on October 03, 2013, 10:51:16 PM not sure, I searched the 0.001 P and all that comes back is 0.001 uf .
Found lots of 0.001 M & Z, no P. Title: Re: Help finding a replacement part Post by: cowboygames on October 03, 2013, 11:12:12 PM 1 microfarad is 1,000,000 picoferads. If you google .001 picoferads there are a few listings. Mouser may have what you need or the people that made the scope
Title: Re: Help finding a replacement part Post by: Foster on October 04, 2013, 05:37:26 AM I think it is 0.001 uF with a tolerance code of P (+100%, -0%)
1 pF is the practical smallest capacitor made. Any smaller and the circuit's parasitic (stray) capacitance would dominate the capacitor when value is below 1 pF.

Any smaller and the circuit's parasitic (stray) capacitance would dominate the capacitor when value is below 1 pF. :212- :212- Ya, .001pF is like .0000000001uF Title: Re: Help finding a replacement part Post by: proten on October 04, 2013, 10:17:44 AM That's what I was thinking but I just wanted
a second opinion. Title: Re: Help finding a replacement part Post by: cowboygames on October 04, 2013, 02:00:52 PM I'm sure Fosters right, but why would they print the cap with the tolerance and not the capacitance? :103- Tolerance is irrelevant information to print on the cap if you don't know the capacitance value I would think.
Ok, I reread his post, I get it now :30- |
