CadSoft EAGLE: Creating a New Library Component
When you're using CadSoft EAGLE for designing electronic circuit boards, sometimes you're not able to find a specific component that you're planning to implement in your design in the available component libraries. If you're lucky you'll find that someone else has created the component and shared his work online but if you're out of luck you'll have to do the work yourself.
This article uses an example component and its datasheet and shows you how to create your own schematic components along with PCB footprints and how to connect those in order to get the correct wiring on your PCB. The component in the example is the IRF7309 dual P+N-channel MOSFET which is an SMD component in an SO8 package.
