understanding part numbers and packages

autodeskguest

I'm very new user of Eagle and I'm trying to understand how to use the

right parts. For example, I'm using a 10K carbon film resistor 1/4 watt

5% tolerance.  I see in resistor.lbr  under  R-US_ RESISTOR- American

symbol package 207/12   (type 207 grid 12mm).  Where exactly do I find

these package numbers?  How do I match my part to a part in the library?

 

Here's the data sheet the I'm using

http://www.mouser.com/catalog/specsheets/XC-600035.pdf

 

What part should I use?

    You don't need to worry about tolerance, eagle is not a simulator so it dosn't matter.

    According to the datasheet your resistor is 6.8mm wide, so you might use 207/10 as

    207/7 is just 7.5mm apart so it'll be a tight squeeze (and you shouldn't bend the wires

    that close to the package - use at last a couple of mm's from the package edge).

     

     

     

     

    And what does type 207 mean? I know it a package but I don't see 207 in

    the data sheet.  What does types 204, 207, 309, 411 mean?

     

    I noticed for  Power Metal Film Resistors in

    http://www.vishay.com/docs/28729/pr010203.pdf

     

    "High power in small packages (1 W/0207 size to

    3 W/0617 size)"

     

    So 207 is the diameter size?

     

     

    (I'm a EE but it's my first time making a schematic to PCB.)
