What component do I have?

I'm new to the forum and I'm pretty sure its for bigger electronics but u thought why not try. I have a component I desoldered from something but I'm not sure what it is. If it helps, the text reads "O4.00F1"

Welcome to the forums.

It looks like a miniature filter in an RF circuit.
It could also be some type of resonator or crystal for a circuit.

I was just thinking.... it could be an I.F. filter in an FM discriminator stage.
4.00 for 4 mghz.
