 Hi Colin,

Some of the small ceramic filters from NTK and Murata have extra ground
pins. I've seen them with three or four ground pins (connected in parallel
internally, evidently), plus the usual I/O pins.

I have a Murata catalog (PDF) that has specifications and pin-out diagrams
of many ceramic filters. If you'd like a copy, let me know and I'll send it
your way.

73,
