Resistors are about the easiest product in our line up
here at Farnsworth Electronics, Inc. We've got
so many drawers full of
resistors that we don't even bother adding them to
our annual inventory
count anymore.
Here's what you need to know
about resistors:
1) Wattage (1/8, 1/4, 1/2,
1, 2, 3, 5, 10, 20, 25, 50, 100, 200, 225, 500 watt, and more)
2) Ohms (wide range from
0.010 to 22meg and more)
3) Tolerance (1%, 2%, 5%,
and 10%) Tolerance the range in
variation of the ohms. For instance,
if you have a resistor that is 100 ohms and
it's 10% tolerance, this means it is + or - 10% of 100 ohms,
therefore your
resistor is actually 90 to 110 ohms.
4) Composition
(Carbon,
Flame Proof, Wire wound, Surface Mount, etc.) |
