Default 100n ceramic disc capacitor

I am new to electronics and decided for my first project I would build a small amp found in the june issue of everyday practical electronics magazine. I think I have gathered all the needed parts from www.mouser.com, except that I am unable to find the part listed in the subject of this thread. I have looked in some books that I have and also online and can't seem to figure out what to do about this. I think this capacitor would also be listed as a .1uF? I just can't find it, is there a substitute for this or does someone know where to find it?

Thanks,
Mark

Umm... This is a really common part, and yes it's 0.1uF or 100nF capacitor.

Well that is what I thought, but I can't seem to find it at mouser, and they are a major parts distributor. I know I sound kind of stupid right now, but I have been looking for over an hour for this part and can't find it. If anyone shops at mouser could you please give me some assistance finding this part. I have found other types of capacitors with a capacitance of .1uf but I can't find a ceramic disk one, and I don't konw enough to know if other types are interchangable.

Well, you usually use the ceramics for digital stuff for higher frequencies and all. But usually with an amp, a 100nF poly cap would be better (not as cheap though). You'd be good with any kind of 100nF cap really, but I'd go with polypropylene.

I'm just fine with multilayer 0.1uF quality caps.
Choice is yours.

Okay, I will take pity on you.

50V multilayer.

Not that I would recommend this cap.

A bit of advice: get the paper mouser catalog. The website is hard to navigate unless you have a part number.

Thanks everyone for your help, I really appreciate it. What I don't appreciate is being insulted by everyone instead of just answering my question. I am just getting started and am trying to learn as much as I can. I have been doing a lot of reading and now I want to work on a few simple projects to get some hand on understanding. Being new to all this I was not sure what capacitors could be replaced for other types if at all.

I read lots of posts here about getting new young people interested to continue the hobby. Well I am one of those new young people. I am not just asking for a handout, or for people to do my work for me. When I post a question I have already done everything in my ability to find the answer for myself. So I take it very offensively when everyone insults me for asking what to you is a simple question. Everyone has to start somewhere, but if you insult every new person like this I think a lot of people will be turned off to diy audio. Maybe I am a moron, fine, but then just don't answer my question, there is no need to make fun of me.

Tiroth,

I am still unsure after following your link that the part listed is a ceramic disc capacitor. It is probobly me not understanding something, but it doesn't specifically say disc packaging, as opposed to the other types. This is why I originally asked the question, because I could find a .1uF capacitor, but I didn't know if it was the right kind. On a side note, great site about rod elliot's project 3A amplifier. I am considering building that amp in the future and your website had a lot of good tips.

Mark

Sorry markkanof if I came off insulting, I didn't mean it that way at all. As for the cap trioth pointed out to you, it's a ceramic 100nF cap, it will do fine for you (I'd still reccomend a poly cap for that value though).

If you want to see it's packaging follow this link http://www.mouser.com//index.cfm?&ha...03&startrow=11 and click on the packaging next to the cap you want (although they're all the same package) so see the diagrams.
