FILTERS
FOR COMMUNICATIONS EQUIPMENT–RESIN MOLDED,
MULTI-ELEMENT–CFUS„Y/CFWS„Y SERIES
The CFUS„Y lines of ceramic filters are
4-element devices connected in ladder
form while the CFWS„Y455 filters
contain 6-elements. These highly
selective filters are designed to address
the G.D.T. characteristics required in
digital communications. The excellent
G.D.T. characteristics allow these filters
to be utilized in areas such as the
mobile cellular markets as well as
a variety of stereo applications.
Available in 450kHz and
455kHz versions.
