It's not found on Google.

It looks like a relay, I doubt you'll be able to get a datasheet for it but you can probably easily figure out the pin out using a multimeter.

If it's not a relay, then I have a feeling, it could be an IF filter, probably 455kHz.

What does the board do?

How about posting a picture of the whole board?

That makes sense.

The original poster really needs to learn how to use alldatasheet.com, datasheetarchive.com,  Google etc.
