0306 pad design | 20 December, 2002

Greetings, Does anybody out there have any experience with 0306 capacitors (not 0603). I am trying to find a pad design for this component. I have searched the archives to no avail. The component is .06 long by .03 wide with .007" solder terminations along the .06" dimension. I am fearful of tombstombing if the pad is incorrect.

Thanks Russ

The total inductance of a chip capacitor is determined both by its length to width ratio and by the mutual inductance coupling between its electrodes. So, a 1210 chip size has a lower inductance than a 1206 chip.

Check with your supplier for recommendations. For instance: http://www.avxcorp.com/docs/catalogs/licc.pdf

Thanks Dave, I was looking in the Murata data base and couldn't even find the part (Even though they are the ones making it)let alone the pad dims. This part looks like it could be fun anyway.
