Gallery Accidentaly bought more resistors than intended....
So I sort of bought all the resistors here by ordering 3 times and forgetting about the first 2 times. Atleast they are not all the same value. Altough i bought double the sets on 2w. Atleast i wont need too be buying resistors anytime soon.

Wanna send me some ressistors? My address is 1600 Pennsylvania Avenue NW in Washington, D.C.

I know a guy who accidentally ordered 5000 reels of resistors instead of a reel of 5000

Ohm. Well he will not need any in the near future if he actually bought them.

That's of the order of half a million USD of resistors. Most likely they were either sent back or a rep called to confirm.
Interestingly enough,would be only about 20 medium cardboard boxes.

Yeah, there's no way that order went through.

u/BurrowShaker 1d ago
Big enough assembly house, could happen. Supplier would be surprised that a single reference is ordered though.

shipping costs way more than the components. And I use resistors by the dozens in most projects. So I have reels (what, like 5000?) of 0604s in a lot of common values. I dont like/use THT as often, but I still have 1000pc of 1/8W resistors in each of the E6 series.

I'm a newb trying to learn electronics and was thinking of buying some components to have for projects. Just accidentaly orderd way too many resistors. Got any tip on an assortment of components to have so I can make all kind of random projects?

- design projects to use parts you already have on hand. dont fall into the trap of ordering a specialized 'perfect' component for a specific task. For resistors, this means you DONT need 1% in every value. For most applications, the next closest value you have on hand is usually OK. Use a 330 instead of a 270. It'll be fiiiiine. Most of the time, at least. Knowing when you must have something specific is an essential skill, instead of always using high precision parts. Do you NEED that precision op amp, or will a 358 work? Do you really NEED every value of every type of capacitor? No.
- I think there are lists of essential jellybean components over on eevblog.
- Find an organization system that works for you.
- Always order spares. For future projects, or plain old f-ups. Especially tiny SMD parts. Drop it on the floor = gone forever.

oh, and when buying from China, ALWAYS test then upon receipt, and be RUTHLESS in claiming refunds when you get parts that aren't what they claim to be. Don't call them 'counterfeit,' - they seem to be sensitive that, but DO show that they arent in spec for what they claimed to be when you bought them.

While the 358 is cheap, it has a lot of limitations - not too good on driving things towards either rails and limited CMM range that limits its use on low voltage design. Almost any of the jelly beans parts from the last 40 years are better.

Only for small quantities. If you're ordering a bunch of ICs at the same time, you'll probably exceed the minimum value for free shipping anyway. Not to say having a large stock of resistors isn't handy anyway. For tweaking values etc.

There's no such thing as too much resistance these days, so congrats!
One thing to pay attention to is to keep unused bags well wrapped as many cheap components from China do not use copper anymore for their wires but rather a very thin coating on iron wires (you can check them using a magnet; copper doesn't stick, iron does). They're mostly ok for hobby projects, also often surprisingly accurate, but could tarnish if left for a very long time in the open, so I would keep the unused one tightly closed in their bags.

If you have this many what feasible project could you build with them? Honest question.

u/Whyjustwhydothat 5d ago
I guess i could do a stupid low resistance kluster of them. Atleast i will be able to overuse resistors for a while. Make everything using like 2x200 to use as 100 ohm instead of a 100 one. And I could also make alot of custom resistances i guess.

Happened to me with cabbages once. I still think fondly of them. Huge bags of em’ eventually they were all eaten.

Why such big sizes?

u/Whyjustwhydothat 5d ago
Too make sure they will hold. Nah but there are 1/4w aswell. Gonna get more sometime.

You can never, EVER have enough resistors

u/shadow-ghost-Victor 4d ago
Well, you got two options either you keep them all or you sell the amount that you don’t need or think you need 🤷🤷🤷

I hope your reselling capabilities are greater than the new "stock" you received..

Aaah, yes- the ol’ “I got drunk and ordered components I forgot about” phenomenon.

I can top that...
I accidentally bought 30,000 plastic push in PCB stand-offs.
I've so far used 3...

reminds me when I tried to buy a resistor kit (500pc, bunch of different values) from a local electronics store, long time ago. I decided to try their phone ordering so I wouldn't waste time when picking up (going there is always a time suck, and not because of lack of staff).
When I got home, I noticed they gave me 500pc of a single value.
Phoned them back to have this sorted, they said to keep what I had, and that they'd phone me back when it is ready as they were out and would need a day or two to make (I think they build the kits themselves). When I get there to pickup the replacement, the employee came out the back with a big box full of the kits. Seems the person I spoke to wrote '500' in both the description and the quantity field...
I played nice, and took only 1 (they did offer I take 2 for the inconvenience, but I felt bad since I already have the 500pc of 4.7k resistors).

ooooh, and these are the expensive kind 😖
At least you can combine them in parallel or in series to get a another resistance value (and therefore a different resistor)

Can you use Ohms Law to convert them into volts or amps to power your device?

Barerly. I'm still a bit lost and need too look it upp every now and then.

When you buy from China, you either buy more than required intentionally or accidentally. 😀
