Footprint Naming for Metallized Film Capacitors

[Ratfink]

I found at least one THT capacitor footprint that needs to be added, and I realized that I don't know what to call it. It's for an ECWF(L) metallized film capacitor, and their shape doesn't seem to match any of the THT capacitor shapes described in F3.3. I could fudge it and call them rectangular, but that's not right for mechanical integration. Then again, our existing capacitor footprints don't seem to be designed for excellent mechanical integration, so maybe that's okay in this case.

@evanshultz @poeschlr @jkriege2 @Shackmeister @Misca1234 Any suggestions on this?

Caps like this and box caps are typically (often?) interchangeable electrically. So they should work fine in our existing rectangular footprints and that's how I've used them (interchangeable on the same AVL).

It would seem that THT Capacitor from F3.3 would fit them, right? The others are SMD.

Since our footprints and 3D models are intertwined, it would make sense to have footprints for these caps (even if they're all copies of the existing box ones). But what to call them that uniquely identifies their body style? I've heard them called "dipped" and used that term without seeing raised eyebrows, but I don't honestly know if there are other or better names for this capacitor body style. http://www.cde.com/capacitors/film/dipped-polyester does use this same term.

THT Capacitor from F3.3 would fit, but there's no specific name for this body style. That's really what I'm asking about: should we make a new style for these or just pretend they're Rect-style?

I agree that it might make sense to have footprints for these separately from the Rect footprints for the 3D models, but previous discussions (e.g. KiCad/Capacitors_THT.pretty#14) have concluded that our capacitor 3D models don't have to get every detail right because it would make the library too big. Maybe this body style shouldn't fall under that line of thought, or maybe it should; I'm not sure.

As for naming if we decide to make a new style for these, Dipped sounds okay to me.

I say call them "dipped" so that the 3D model can match the actual component.

If the user picks either footprint but allows both dipped and rect caps in that location, I think we're still good. In other words, I don't see anything that breaks and since these are scripted there isn't much overhead.

We are also missing dipped tantal caps. So we might need to take them into account when we make a final naming convention.
