content: Hello everyone this is a really silly question but bc i don't know a whole lot i just need someone else to tell me that it is ok.for a project that i will be doing i was told to use an .001 microfarad ceramic capacitorbut on the web on digi key i could only find, an .011uf could i still use this for my project,?I believe that i could and it really would not effect much.here is the link to the item.http://www.digikey.com/product-detail/en/ECW-F6113JL/P12112-ND/585179

content: Look for 1000 pF. You will find the cost much more reasonable. That's not ceramic, anyway,though it will work. (Edit:I misread that as 0.0011 uF)

content: Sounds like someone was having a laugh at your expense. Just be grateful they didn't advise you to use a 0.000000001 farad capacitor

content: Most capacitors are +/- 10% to 20% anyway. Unless it is used for timing (and there's no fine adjustment).The ONLY other thing to watch for is material type. ie Ceramic, polyester, silver mica (rarer), thismaybe important.Do you know what its purpose is in the circuit?

content: 0.011uF is eleven times the size of 0.001uF.In some circuits it may not matter,in others,it will prevent it working correctly.For many years,the only subdivisions of Farads used were microfarads (commonly written as uF),& picofarads (written as pf).Modern usage has changed to include nanofarads (nF).0.001 uF is the same as 1.0 nF,so if you shop for that value,you will be able to easily obtain them.

content: Quote from: DellyjoeWe all did fun circuits when we started. Most likely it will form one of the bandpass filters, in which case changing the value may alterwhat frequencies pass through that filter > light. You'll probably want to fool with these caps anyway to see the effects.
