EAGLE Packages for resistors

  1. I have purchased some 1/4 W Xicon resistors from mouser, part number
    30BJ250-470.

    I am trying to choose the correct package from the rcl library under
    CadSoft's EAGLE program for these resistors. I find choices like
    204/7, 207/10, 309/12.

    I don't recognize anything in the Mouser web pages or the Xicon data
    sheet that gives me any clue. I have pretty much settled on the
    207/10 description as the one that matches the actual specimen length
    and diameter correctly.

    Can someone help clarify what these package designations mean or where
    they are documented?

    (Win, an appendix in the next AoE?)
     
  2. Might be a good question for eagle.support.eng, on server news.cadsoft.de -
    that is, Eagle's tech support. I don't think those are standard package
    designators that Eagle uses, though I could be wrong. The /7, /10, and so
    forth are mm of length (approximately 2.5mm for 0.1 inch, so /10 is 0.4").
    I suspect the first number helps specify the width but I'd have to go look
    to test that theory.

    That's the size of the resistor, according to whatever standards
    institute (CECC?)

    0204 are those small (typical 1/8 W) resistors, about 5 by 1.5 mm.
    0207 is the standard size for 1/4 W, about 6.5 by 2.5 mm.
    0309 and 0411 are the next larger sizes.

    If the 0207/10 packages work, use them and be happy :)
