[sdiy] reading blue 5 band resistors...

[Tim Parkhurst]

Hi Edward,

The blue ones are "precision resistors" with a 1% (or better) tolerance. The
brown resistors you are used to seeing are usually 5% or 10% tolerance. The
blue ones are also usually a "metal film" resistor which is less noisy and
slightly less temperature sensitive than the brown ones (the brown ones are
'carbon film' resistors). Precision resistors are a little more expensive
than standard carbon film types, but lots of DIYers prefer them.

Precision resistors (tolerance of 1% or better) have 5 color bands to
indicate their value and tolerance. Here is a link to a chart that shows the
4 band color codes for standard resistors AND the 5 band codes for precision
resistors. Check it out at:

Hope this helps. Happy hacking!
