Claimed "1/4 watt" through-hole resistors from Amazon seller "Eamasawa"

Siwastaja:
When you need specifications, and parts that comply to said specifications, only buy from electronics distributors such as Digikey, Mouser, Element14/Farnell, or even lcsc.

Only buy from Amazon/Ebay/Aliexpress when the proper distributors are a non-option. Some trivial connectors being horribly expensive at the distributors, but cheap and good enough on Aliexpress, comes to a mind as an example.

But resistors are cheap even at the distributors. And you get the specs!

Simon:
Amazon was never created for electronic components and yes many of the descriptions are useless. I often don't buy because clearly the seller is clueless which means I'll get wrong goods. As a seller myself I take pride in the fact that I know what I am selling and can answer technical questions. Amazon is just like ebay in fact both have been approaching each other in terms of practices baring ebay forking out for warehouses to try and take each other out.

Sadly i could not compete with the likes of cheap chinese crap on ebay or the universality of Amazon and gave up on small parts years ago moving instead to very specific products that are not available everywhere as they are more niche.

Alti:
For breadboarding LEDs, SMPS and digital you need E3, maybe E6, 5 decades, maybe 5% 400ppm if you are picky. But for analog electronics you need E24, 1%, 50ppm at least.
Although you rarely need sub 1R values for analog electronics, >10M is not uncomon.

So, do not bother with Vishay pullups and do not bother with carbon resistors for analog electronics.

IME there's nothing really new. I have seen this happen with capacitors of all brands for ages now... I usually store the bits I clip from the original leads and over the years I can tell which ones are newer and older. The first shrinking leads I saw were about twenty years ago when 1/8W through hole resistors started to become popular.

So analog electronics did not exist before the 1960s-1970s when virtually all resistors were carbon composition?  I agree that carbon composition has many drawbacks, but it is often suitable to purpose, even in analog electronics.  If you are good enough to design such that the specs on resistors matter you should be good enough to spec resistors that meet the needs of your circuit.
