Today I purchased 1,200 1W 1% metal film resistors for my lab. Particularly I wanted a bunch of disposable resistors which I can use once in a soldered circuit which I will throw in the junk box when I’m done with it. The main application for that at the moment is my Learning the Art of Electronics project which I’m working on. I only had space for twelve varieties and I got 100 of each type. Being 1W rather than the typical 1/4W makes them a little more forgiving on the bench in the case of overload and the 1% tolerances keep things nice and tight. The values I picked include:

• 10 Ω
• 100 Ω
• 470 Ω
• 1 kΩ
• 2.2 kΩ
• 4.7 kΩ
• 10 kΩ
• 15 kΩ
• 20 kΩ
• 47 kΩ
• 100 kΩ
• 1 MΩ
