I am looking to use some feedthrough capacitors in some design I am working on, however there are currently no footprints in the libraries. Before I start creating & submitting footprints, I'd like to ask for opinions on how to go about it.
All have slightly different recommendations on land patterns (if any!)
Questions:
1: Does anyone have access to the IPC recommendations? (if any!) - I have no idea if feedthrough caps are included or not.
2: Are these footprints we could script?
3. Would a single generic footprint be OK, or should we use manufacturer-specific footprints?
4. What library to put them in - Capacitor_SMD or Filter?
Thanks,
James

See pointhi/kicad-footprint-generator#438, at least one outdated IPC-SM-782 document is linked there.
That generator is also partially related, it does RLC footprints.
2: Are these footprints we could script?
Yes but .... AFAIK there is no script that can handle it. It needs to be created. Those parts a rather special, so it is not mandatory to script them.
Would a single generic footprint be OK, or should we use manufacturer-specific footprints?
Depends. I would start comparing them and see if there can be a consensus footprint.
What library to put them in - Capacitor_SMD or Filter?
Everything is a filter if you are brave enough! Capacitor_SMD sounds better to me, but I have no arguments.
