I'm doing a PCB design in Altium Designer where I would like to include a feedthrough capacitor from Murata (MPN: NFM18CC101R1C3D). This is a special type of capacitor with 4 physical terminals where two of them are internally connected, i.e. 3 logical pins. I have not been able to find the component anywhere and the "IPC Compliant Footprint Wizard" does not include a such footprint.
My question is: What is the best way of making this type of component in AD
- Would you create 4 pads in the PCB editor where two of the pads have the same designator?
- Would you include the 3 recommended through-holes as part of the component or would you just include them as free via's in the board file?
- I would like to have the board produced at Seeedstudio which accepts a minimum via dimension of 12mil (0.305mm) hole and 25mil (0.635mm) diameter. Based on this I don't think the inner through hole will be possible to make. Can I simply skip this without having to worry too much about lost performance?
I'm looking forward to hear you suggestions.
Best Regards, Andreas
