Does anyone know of a U.S. distributor that stocks 70 MHz Monolithic Filters? I need a couple for a project but Mouser and DigiKey do not stock anything over 45 MHz.

I want to use a 4 Pole filter to obtain a more narrow bandwidth than a 2 Pole would have. I can use either a through hole or SMD part.

Not US distributor, but Czech mfg. However they will gladly make even customised values of crystals and filters.

Kony, thanks for the suggestion. Unfortunately, shipping to the U.S. would probably cost more than the parts. Maybe something will turn up on Ebay.

If you find a distributor for such things please post it. There are a lot of really neat filters (e.g. SAW) but no one stocks them.

Not exactly what you asked for, but you might look at what else they have on offer.
