<x-flowed>That sounds like a ceramic resonator with built in caps.

       It's a ceramic resonator with built-in capacitors. My favorite supplier
is murata. Check out their "resonator search" at
http://www.murata.co.jp/search/ic-e.html .  You put in the chip you're
using and it tells you which resonator to use.

Hello all, I am once again back on the PicList.
OK, I am looking at someone else's board.  I see a yellow 3 pin thing in
place of the xtal.  It looks to me like the center pin is tied to ground
and the other 2 are going to OSC1 & OSC2.
I love to reduce part count and want to know what this is..  It looks like
a tantalum cap with 3 pins and has 4.00u on it, my guess is it is 4.0Mhz.
Is it RC? or Xtal with caps built in?  Who sells them, who is the mfg?

Best regards,
Giles

<x-rich>It is probably a 4 mhz ceramic resonator with the caps internal to it.
Like a crystal with the 2 caps but not as precise.
