Does anyone know where I can find spec on this kenwood yg-455cn-1
filter.

Attenuation band width: 480 Hz (-60 dB)
Guaranteed attenuation: More than 80 dB

I should have been more specific. I need the pinouts. I was hoping to
find a datasheet. I'm not going to use the filter in a Kenwood radio.
Basically, it's a flea market find.

Do a search for International Radio or InRad. They might be able to help you
out.

It helps in the sense that I now know the impedance is 2000 ohms,
assuming the InRad filters are the same impedance as the other
kenwoods. With equal impedances (sort of what I expected), I assume
that input and output can be interchanged..

BTW, thanks for the quick reply.

A quick Google search says it's a 250hz cw filter for radios with a 455khz IF.

I didn't see any an indication of if it's a crystal or mechanical filter, or
what the shape factor should be.

It is a crystal filter. That is marked on the case. I picked one up at
the local flea market, but need to figure out if it is useable in my
radio.

There are 5 pins per side. The ground and signal lines are obvious, but
that's about it.
