Standard parts values? - Parts library.

(1/3) > >>

Hey everybody,

I am ordering some parts to start making things with. I already have a good background in electronics and everything, I'm just starting to get serious and actually buy some real things.

I'm wanting to order some of the standard parts such as resistors and capacitors and everything but I don't know which values I should get. Like I know I should get quite a few of 0.1uF caps, but like other values, and different types (electrolytic, etc...) I don't Know.

If anyone could shed some light on the most standard and used values I would greatly appreciate it. I realize that there are probably some times that I will need a special value or whatever, but I'm just looking for the most useful so far.

Also if there's anything else that I've skipped over that I will need, I would be thankful for such information.

Here's what I have so far. Please correct me if any of these are probably not good.


0.1uF Ceramic (?)

Crystals (for microcontrollers):

Anything else?

Any information would be greatly appreciated.

Thanks in advance,
P.S. Is it just me, or does anybody else have the same problem. Whenever I type a post on this forum, once I get to a certain length, the text i'm currently typing goes below the text entry window. Every time I type a character, it jumps back up real fast and then drops below again. I don't know if  I have a setting wrong or something...

Professor Fudge:
Thanks for posting this because I was wondering the same thing.  :D

Something to add to the list.

Timer 555
Voltage regulators: LM7805, LM7812, LM7905, LM7912, LM317
22pF capacitors for the XTAL osc on the microcontroller
Electrolitic capacitor: 10uF, 100uF, 22uF, 47uF at least 25 v
Diode 1A
Potentiometers: 5K, 10 K, 50K

well and more....

Some electronics stores sell 'grab bags' of common components. It's not a bad idea getting some of these, just to have every 5% resistor value on hand. Same goes for ceramic and electrolytic capacitors. eBay is a good place to find these at very low prices. Values like 10nF and 100nF ceramics, and 10uF tantalums are handy and never go out of style.

There's a few good threads somewhere, try searching for 'jelly bean' and see what pops up.

Knowledge of the E series system will help you understand why resistors and caps have the value spreads they do. Sometimes you can find kits of a full series, though they tend to be expensive.

I always recommend salvaging parts from old electronics if you have the time. I find it relaxing and a great way to stock up, but many folks would rather spend their time building than destroying. It's good practice desoldering though. :)
