These are 1/4th Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 100 Ohm resistors make excellent pull-ups, pull-downs, and current limiters.

Note: Although these come in bags marked with a quantity of 25, they don't always contain 25. So we'd rather call it 20 and hope that you get extras.
