Hi,
I've got an inductor I was hoping to include in a design but haven't had any joy finding an equivalent for EagleCAD. The component is a Pulse Engineering 100uH inductor, PE-92108 (datasheet linked here (http://www.farnell.com/datasheets/24270.pdf)) which is spec'd as being a KlipMount KM-4.0 package. Can anyone suggest an equivalent I could substitute, an alternative name for KM-4.0 from another vendor with an EagleCAD presence, or a library containing the real deal?
Thanks
Geoff

Unless you find the substitute, it is very easy to make your own library with Eagle. See Chapter 8
Component Design Explained through Examples in the manual for version 5 for instance.

Thanks Bambur. So far I've not had success finding a substitute so I have been reading up on how to make my own. It doesn't seem too hard to adapt something with only 2 pins from one of the existing packages so will give it a go over the weekend.
-
In the datasheet link you provided, it even supplies the suggested land pattern. If this is a one off thing, just place 2 or 3 holes the correct size and spacing on the board. There would not even be a need to setup a library item then. Although as Bambur has eluded to, making library components is easy as well as being a useful skill in the future.

Yes I quite agree. And I don't think I'll get to start on anything simpler than a box with two pins ;)

Hello Guys
I am also using a toroidal inductor in my design have spent a couple of hours browsing the internet and I haven't had any luck. Before I go ahead with designing my own footprint from the information provided in the datasheet, I would like to ask if stryker has managed to make one.
Cheers

I sure did. I made a footprint for the one I was using and it worked a treat. Apologies for the hurried blurry cameraphone image...
Unfortunately this must have been one of the last things I did in Eagle before a hard cut-over to KiCad so I don't think I still have this. What I can tell you (and I'm hoping you take this as good news) is that coil silk in the middle looks too good to be something I did with EagleCAD so I think all I must have done is found an existing inductor, and adjusted the pin spacing and bounding box.
-
I agree. EagleCAd is comparatively easy to work with and adjust the pin spacing and bounding box.

Amazing... you spent a couple hours looking for a footprint that you could have made yourself in less than 10 minutes?
Seriously, you need to know how to make proper devices in EAGLE (symbol + footprint + pin assignment = device) and a toroidal inductor, with just two pads, is a really good introduction to this.
