Components : Resistors : Finder

Enter the ohmage and tolerance of a resistor to see what it would like like.

Note that not all resistances are commercially available. E.g. there is no such thing as a 123000 Ohm resistor. Standard values are: 1.0 , 1.5 , 2.2 , 3.3 , 4.7 , 6.8 in the E6 series times 1, 10 , 100, etc.... Press the button to find a pair of resistors which best approximates your desired resistance when connected in parallel.
