Victor,
John's correct about your parts being feed thru capacitors. We use lots
of these parts on our products. Most of the time we refer to them as
EMI filter or low pass filter capacitors. The two terminals in the
middle of the sides are ground terminals.
Regards,
George

This is easy,
It's a feed thru capacitor. It could also be an X2Y capacitopr pair but
the
board is not layed out for minimum inductance so we are back to feed
thru.

Hi Victor,
Sorry for not getting your pictures posted sooner. I've been busy with a
fire here...
Anyways, got your pics up now:

I'm not an electrical engineer, but I do know that they are filter
capacitors used to help with EMI. We place a lot of them on quite a few
assemblies.

Fellow TechNetters:
I have a ceramic component, capacitor, with four solder joint
terminations. My main concern is the component body size to copper pad
ratio. Do they violate IPC standards? I sent Steve G. some photos to
upload to his web page.
Victor,
