21k Ohm0.25Watt Resistor

These are your run-of-the-mill ? Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and other prototyping applications, these 21K ohm resistors make excellent pull-ups, pull-downs and current limiters. These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project!
