most common resistors used (add surpluss to mouser order)

[krem]

Hello, I'm in the process of ordering up some components from mouser and was
wondering if there were any suggestions as to what to buy in order to "stock
up". The shipping is a hassle for me mainly because the cost of the
components are virturally the same as shipping would be. I do try to
double+ my volume in order to be able to produce more than one device if i
so chose but i'm looking for suggestions as to what to add to my order.
Just so i don't have to make so many frequent purchases. I'm not a complete
newbie but i've been pulling components from destroyed equipment and this
has grown tiresome. Again any suggestions or recomendations are welcome.

I know how you feel. I t somehow seems unreasonable to pay $5 for shipping
for $2 worth of parts. I guess we should be happpy there's no minimum and
the parts are so cheap.
I usually look at what resistors I have, and try to fill in the gaps there
(I know there are a lot of values, but just start by ordering 10 or so of 5
or 10 values you don't have). Also, I'm pretty sure that Mouser's metal film
resistors are as cheap (or cheaper?) than there carbon, so keep an eye out
for that. I may be wrong - maybe it's Newrk that has them cheaper.

I don't know about Mouser, but DigiKey has kits with the most common

values. I try to keep all the 10% values in stock from 100 ohms to 1M,
with a few "specials" like a bunch of 51-ohm carbon compositions since I
do RF work. So far my lab is nearly all through-hole, but that'll have
to change soon.

any suggestions as to what to buy in order to "stock up"

For me, the thing about resistors is that they are these tiny parts
and most folks use regular Akro bins
with drawers many times larger than required.

Real resistor bins (requires buying a standard "assortment") seems smart.

1K, 4.7K, 10K. Seems those values are the one's
I order most often as "fillers". I must be using
them more often than the other values. Keep a list
of what you use - over time you'll see which ones
to order as "fillers".

If you don't yet have an assortment of 5-10 each
of the most popular values, find one and buy it.
I did a search and came up with:

(Look out for the line wrap) and
http://www.iglou.com/studiosound/resistor.htm

The above references are cheap starter kits of carbon
resistors. You'll likely "graduate" over time, but
they give you a base to start from.

If you are going to be doing a lot of building, you'll
need hardware. 6-32 screws, nuts and lockwashers to
start. Hookup wire, solder, switches, - think of
common stuff you'll use for any project.

By Sod's Law you won't have the value you need, but 100n ceramic caps,
1N4148 and 1N4002 always come in, and 2N2222A is a good GP NPN. Depends on
the type of thing you build, I usually work on 12v or 9v supply so 16v
electrolytics are OK to stock up on. Resistors get a pack of E24 and extra
1k, 4k7, 10k, 47k and 100k

Although I'm in the UK, I tried Futurelec recently as prices were good and
the delivery to the UK ($3) cheaper than the delivery charges from my usual
UK suppliers. http://www.futurlec.com/Components.shtml

Screw that! Go E96 all the way, and get the tighter tolerance, and
better temp coefficient, and have higher reliability circuits in your
designs.

Otherwise good advice. I'd get one of every ten ohms to a hundred,
and every hundred ohms to 1k, then go by your steps at 1/4 watt. Get a
set of 1/8th watt as well, if it is in this particular plan or budget.
You won't regret it. Of course get the values that are close to the
points mentioned as the exact "every hundred ohms" values are not what
is available.

As for what is available, download my PDF form drawer placards,
freshly posted in alt.binaries.schematics.electronic.

One can use them to mark the drawer fronts of one's resistor
collection(s) as well as for "flash cards" they teach well.

Don't forget to download the resistor decoder chart as well!
