This is a 20 Pack of 200 Ω Resistors. More specifically, they are carbon film, through-hole axial type, with 1/4 Watt max dissipation, 300Vmax voltage, 5% precision resistors.these 200 Ohm resistors make excellent pull-ups, pull-downs, and current limiters.

Well, These are super common and great for use in any kit, breadboard, perf-board, or other project. We got ones with 0.4mm thick wires so they plug in nicely into solder-less breadboards.
