TO-220-11 library for expresspcb?
 
Does anyone have To-220-11 library(pcb component) for expresspcb.This is for a lm3886 chip. How to go about creating a pcb component for 3886 chip.Should I look at the data sheet pin distances adn then try to consturct the same by setting grid distances.

Can anyone tell me a simple way to do this.

I have made the PCB component (LM3875) myself. I suppose this has the same sizes. You can take it from the attached ExpressPCB file and copy it into your PCB drawing. Hope this helps.

turn off "snap to grid" which may be set at 25 mils.
