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, Guy Atkins Puyallup, WA USA http://fivebelow.squarespace.com > Date: Wed, 3 Feb 2010 12:05:21 -0800 > From: [email protected] > To: Mailing list for the International Radio Club of America > <[email protected]> > Subject: c > Message-ID: <[email protected]> > Content-Type: text/plain > > A list member has sent me a Sony M37V that I have offered to > change the filter for him. > > M37V and new filter received. > > Sadly - incomplete dis-assembly instructions > and no mention about the fact that the replacement > filter has way more pins that the stock one. > > Anybody done this mod that wishes to share the secret > process? > > > -- > > .......................................................................................... > Colin Newell - Editor - CoffeeCrew DOT Com --- > Victoria, British Columbia - Blog - Coffee DOT BC DOT CA > DXer DOT CA and Bob Harris DOT Com > ------------------------------------------------------------------ > _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
