    It seems standard resistors are tan, but what are their blue, green
    etc. bodied buddies?
     
  2. Most of these have an extra color stripe, so they are 1% or 2%
    tolerance resistors. Some are higher quality metal film resistors etc.
     
  3. Oh, and the green ones with silver stripe are sometimes capacitors,
    especially if they are a dad thicker than resistors. Commonly found in
    smoke detectors.
     
  4. Those are inductors, not capacitors.

    news:...
     
  5. 1% resistors often have blue bodies, but odd body colors (white or
    blue) sometimes imply fusible or flame proof resistors (that function
    as a fuse and resistor in one package).

    Green units are often inductors. If you suspect an inductor, measure
    the resistance and see if it is close to what the bands code. If the
    measured resistance is way less than the code, you probably have an
    inductor.

    But there are lots of variations:

  6. Philips (now BC Components) uses different colour resistor bodies to
    distinguish between different resistance material - carbon film, metal
    film, etc.

    They (the blue ones) are a pain in the ass to read. They
    probably are the reason Ohm-meters were invented. The green
    ones (as others have pointed out) may actually be inductors.

    My dad was much thicker than that.
