Footprint Template for Axial Resistor

 1. Begin by opening the Ultra Librarian software. Once the screen below is shown, click on “Create New Footprint”2. A list of Lead Type and Arrangements will appear. Click “Through Hole”.3. All the Through Hole styles will branch out beneath “Through Hole”. Click “Axial”. A list of all the Through Hole, Axial Templates will appear in the box below.

4. Since in this case we are building a resistor, choose the “*_ADI’s Res, thru, non-calculated, Axial, Nonpolarized” template. Verify you have chosen the correct template by:

  • Reading the full name and description in the upper right corner of the window.
  • Revising the part schematic on the right side of the window. You may click on the image to shift between different images showing different schematics and/or pin diagrams.

If all of this corresponds with the part you want to build, continue by clicking “Select to Build”.

5. This screen allows you to enter all the measurements to create the footprint. A few things to notice:

  • At the top of the screen, the name of the footprint is shown. This is a generic, auto generated name; “RC” indicates that it is a resistor, while the numbers correspond to the measurements of the footprint.
  • You may edit this name in the “Specific Name” box on the top left part of the window.
    • For this case, make sure to leave the footprint name as is; to do so, do not enter anything in the “Specific Name” box.

Click on “View Input Details” to familiarize yourself with how the measurements you enter affect the dimensions of the footprint.

6. The “Input Details” screen will appear, showing how the dimensions in the diagram correspond to the measurements you enter. Most of the time, most of the measurements are found in the “Part Information” section of the footprint template.

7. Upon revising the datasheet for your chosen part, you see that the some or all of the dimensions correspond with the dimensions in the “Part Information” section. In this case, the CF/CFQ18 family of resistors has the following dimensions (Note: Ultra Librarian uses mils by default, so the following numbers correspond to mils):

  • Body_W = A = 0.130”
  • Body_H = B = 0.067”
  • Max Component Height Z = 0.067”
    • It is the same as Body_H because the part is round.
  • Min Component Height Z = 0”
    • It is 0 because the part touches the board.

Meanwhile, there are other dimensions that must be calculated.

  • CG = A+(8*D) = 0.338”
    • Round this measurement to the next 100 mils, therefore = 0.400”
  • DRL1 = D + 0.010”= 0.026”
    • Repeat for DRL, found below
  • PADW1 & PADH1 = DRL1 + 0.020” = 0.046”
    • Repeat for PADW & PADH

8. Enter the dimensions in the highlighted areas. Once done, click “Verify”. If there are no errors, click “Done”. And you have completed creating your footprint!
