content: 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) 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?ThanksGeoff

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

content: 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.

content: 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.

content: Hello GuysI 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

content: 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.

content: I agree. EagleCAd is comparatively easy to work with and adjust the pin spacing and bounding box.
