These 330 Ohm 1/6 Watt, +/- 5% tolerance carbon film PTH resistors are great for limiting current LED's from microcontrollers and in breadboards
These resistors are rated at 330 Ohm 1/6 Watt and work well when you need to drive a standard LED from a breadboard. Using Ohms law these resistors are a nice value to get a good light from most basic LED from most 5 and 3.3V applications.
The leads on these resistors are nice and thick so they are easier to stick into a breadboard without bending a lot.
