Hey everyone! I had a question; I am about to order some parts from Digikey and I as a new aspiring DIY tech guy I was wondering if anyone knows if there is a complete "technician" set of capacitors and resistors and/or any other parts I can order? Or are these parts, just purchased as needed and accumulate as you go along?
Thank you!
Thank you!
Sorry, I mean, should or can, I purchase a set of capacitors or resistors or do you just buy they one by one as needed?
I believe @simon7000 got me 🙂 Thank you but I do not see capacitors and other components like resistors
I think I found them there now though thank you! Stuff like this:
493-SNAPKIT2 Nichicon | Kits | DigiKey

Active parts like transistors, ic's , even capacitors get from a good supplier, like digikey.
You can buy kits of 600 ,1000, resistors for very cheap on other sites. You'll find them useful for various projects, for testing.

In my opinion, yes. You ll need them everywhere, at least for testing.
You can get metal film resistors for projects that matter or you want to keep.
But " standard" cheap resistors will do just fine as well.

Some resistor assortments might be worth it if they're VERY cheap, like a quarter-cent each...

Resistors are available everywhere in kits in 0.25 or 0.5W versions.
Caps have a lot more variables - ceramic, film elco, different voltage ratings etc so kits not as useful.
Look at the projects you aspire to and buy a few values based on those for stock. Or each time you buy for a project, add a few for spares.

Metal film are the standard cheap resistors these days (through-hole at least!). Never any good reason to buy carbon resistors now.
I always buy in bulk to have basic general purpose stock, plus whatever's needed for specific projects.
I suggest:
100 each of:
1-2.2-4.7-10-22- 47-100-220-470 ohm
1-2.2-4.7-10-22-470 kOhms
1 M
all standard carbon or metal film , 1/4W
Other values, say 3k3 , 68k, whatever, same specs, but 20 of each.
Some values in 1 or 2W dissipation, as needed, 20 each.
100 each of:
100-220-470-1000-2200-4700 pF ceramic, .01-.022-.047-.1 ceramics,
.47-1-10 uF electrolytics by 25-50V
20 each 22-47-100 uF by 25-50V
10 each of 470-1000-2200 uF by 50V
50-100 each of general purpose signal transistors, NPN & PNP
I use European types BC547-557 , pick those most available near you.
All this stuff is VERY cheap and saves you countless times, add to this very basic list whatever specific projects demand.
Also:
100 1N4007
50 1N5404
25-50 TL072
10 each TL071 & TL074
50 RED LEDS
20 15-16 V 1/4W Zeners
5 each TL7805-7815-7915
This list fits in a shoebox and covers tons of bases.
In a pinch you can get other cap and resistor values combining these.
Using 2-3 components instead of the "proper" one looks "ugly" and seems wasteful but definitely beats wasting 1 week to get parts in the middle of a job plus paying $5-12 postage for a 10 cent part.
As long as you work and get experience you will add to this basic list.

Skipped some values ☹️
To
1-2.2-4.7-10-22-470 kOhms
add 47-100-220 kOhms
I am using an old convention, very popular up to the 50s, a scale called the "1-2-5 progression"
You might also add values starting with 33 and 68 to better fill the gaps, at least in resistor values.
Again, this is just a handy "backup parts" list, good to have within arm's reach; specific resistors - capacitors - transistors - ICs - pots - connectors -switches - fuses specified in various schematics will be ordered as needed.
Murphy's Law states that you may have 10000 components on hand, you will still need the one you don't 😫
