Overview
Attenuation (dB) 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.
) FEATURES s High selectivity s The pass bandwidths from 30kHz to 4kHz are available.
s Easily mountable onto printed boards s Operating temperature range: –20°C to +80°C Storage temperature range: –40°C to +85°C DIMENSIONS: mm 8.
