Where to find cheap general purpose resistors?

Typically, 1% thick film resistors are used as general purpose SMD resistors. Most of these are spec’d with a 100ppm/°C temperature coefficient.

From all the “normal” distributors, in my experience LCSC has by far the cheapest resistors - around 3€ per reel (5000pcs) of 0603 resistors. Note, however, that they charge around 35€ of shipping to Germany. So you have to buy a lot of resistors in order to compensate for the expensive shipping. However, you can also order other components on LCSC (they’re usually quite cheap, especially for passives and other standard components).
