Default Identify component "BCF JW 455B G"

Hello all.
Can anyone help me identify this component?
I have looked up the numbers but have not been able to come up with anything.
It is approximately 10mm x 7mm with 3 pins. The only markings are "BCF JW 455B G"
The black area on top is just a shadow, the component is all red.

Thanks!

Are you trying to replace it or just identify it ? I would cut it open, it looks as though it might be a potted circuit of some kind.

Looks like a 455kHz ceramic filter from the IF of an AM radio.. Toko, Murata and others make similar devices.

Thanks for the replies!
Good call kevinkr...
Just trying to identify. I scavenged it out of a Sony clock radio. At first I was thinking it was a square capacitor but of course it couldnt be having 3 pins. Then possibly a crystal of some sort.

It looks a bit like a Toko part number. It is a 455 kHz ceramic filter.
AM radio uses a 455 kHz IF centre frequency
