Thanks! I will buy those values.

Where would you buy from? Spark fun does not have any.

Bought from both of these guys.  Jameco I have bought their transistor, diode, and 74LS kits.  The cheapo chinese dudes, capacitor kits and resistor kits.

http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_130232_-1  (Jameco has very fast shipping, typically same day, will get it to you quickly, very reptuable.)

http://www.ebay.com/itm/50value-1000pcs-Ceramic-Capacitors-Disc-50V-Assortment-Kit-/251204208418  (excellent value, low cost barrier, may take 2 weeks to get to you.)

http://www.ebay.com/itm/36value-3600pcs-Ceramic-Capacitors-Disc-50V-Assortment-Box-Kit-/251120210678 (very good value but more expensive for a larger kit, may take 2 weeks to get to you.)

A few other interesting capacitor kits:

I have only come here seeking knowledge. Things they would not teach me of in college.


I use 10, 22, 47, 100, 220, 470uF electrolytics all the time.  For bigger projects (mostly audio amps) I use 2200uF in parallel.  I keep in my stash a complete assortment:  0.1, 1, 4.7, 10, 22, 47, 100, 220, 470, 1000, and 2200uF.  I keep 25v and 50v varieties up to 1000uF, and 35v and 50v for 1000uF+.  Although, due to size and cost, I'll often order the larger ones per-project.  Remember, electrolytic caps age, so order in smallish batches and FIFO them.

The only ceramics I ever seem to use are 100nF for decoupling, 20-27pF for crystal load caps, and 470pF for the timing circuit on a particular switching regulator I use.  I haven't found a need to have an assortment, although that could just be my usual areas of design interest.

I did order a bunch of mains-rated ceramic caps for power switch arc prevention, but I have yet to use any.  I ordered way too many different sizes here.  One or two to pick from would've sufficed.  They just take up space in my kit now.

I was about to order, but I did not know what tolerance is good: 1% 5% 10% 20% ?  What would you recommend?
