FILTERS
CERAMIC FILTERS FOR AM APPLICATIONS–HIGHLY SELECTIVE CFU SERIES
The CFU 455 line of ceramic filters are 4-element devices connected in ladder form while the CFWS 455 line of ceramic filters contain 6-elements. These compact, highly selective filters are recommended for use in applications ranging from two-way radio to auxiliary filters in high class transceivers. (Also available in 450kHz version.)
