CFZM455D

FILTERS FOR COMMUNICATIONS EQUIPMENT RESIN MOLDED, MULTI-ELEMENT CFVM/CFZM SERIES The CFVM line of ceramic filters are 7-element devices connected in ladder form while the CFZM line of filters contain 9-elements. These highly selective filters offer improved stopband attenuation and are recommended for use in a variety of applications. Available in 450kHz and 455kHz versions.
