QMX+ Vishay NPO 680pF capacitor spec #parts


 

I cannot believe that I put C515 where D508 goes.? Stupid mistake.? Discovered it right away, but I destroyed the part getting it out.

I need to buy a replacement. I see it is 680 pF NPO by Vishay, but I do not know voltage, tolerance, etc.??

Also, if you have a favorite US source for low quantity orders, I would appreciate it.??

Thanks,
Mark


 

Yeah, it's hard to get around shipping expenses for onesy-twosy parts.

Digikey and Mouser are reliable sources, but not set up for small orders. (I think if you look closely you can find a cheaper shipping option for Digikey.) Adafruit is not unreasonable for shipping. Or Ebay, while slightly more risky, often has people shipping for free.?

Sorry I don't have the part spec's for you.


 

No replies yet on the specs for this capacitor.? This is in a low pass filter, so it will see some voltage.??

Based on the markings, this is a Vishay/BC capacitor.??

On Digikey, I see a 50V 5% NPO through-hole 2.5mm spacing that looks similar. No minimum order and less than 6 USD for 3-day shipping to correct my mishap.

My only question is whether or not 50V is enough for this application.

Any idea what voltage the lowest frequency LPF might see?

Yes we use the 2.5mm spaced 50V rated Vishay NP0/C0G from Digikey. The price for US domestic shipping is $4.99.?
