Coomon Cap + Resistor Values

[echen1024]

Well, I'm about to stock up again at Digi-Key, so I wanted to know what value resistors and caps I should get, and are just good to have around. Any other components are welcome as well. I do have an extensive 74 series collection, so keep that in mind.

This question has been asked before.

A lot of the advice given around here is to just buy what you need for your current project, plus five or ten to go in your parts collection. Beyond that, you could try ordering values from the E12 series, or maybe E24 if you have the space and budget.

Since you're in the US, Radioshack sell a big pack of assorted resistors for about $17, IIRC. I don't remember exactly what's in it, but they're all fairly common values. They don't have much in the way of caps, though, so you'll have to order those.

Well from what I've seen most resistors and caps come in these multiples (commonly)
1's (1,10,100,1k,10k,100k,1M,10M etc)
2.2's (2.2, 22, 220 etc)
3.3's (and so on)
4.7s (and so on)

Also, if you haven't checked already, give Tayda a look. I ordered all this for about $25 including shipping (the end number is the quantity)

For a more evenly spaced resistor series: 10 18 33 56 (each is 1.8 times the last, including 56 -> 100). That way you are more likely to have the value you want.

You could do 10 20 30 39 as well, making it easy to stack a few in series to get the value you want, if you don't mind stacking them.

I actually just bought a cheapo E24 pack on eBay, then tested which were not within tolerance and bought those on my next Mouser order. I specify SMD resistors at E24, so I want the same set for prototyping.
