Communication Ceramic Filters
(LTM 455/450 U/W)
Introduction (LTM 455/450 U/W)
Token communication ceramic filter is Murata CFUM/WM 455/450 compatible. Token ceramic filters for communication LTM 455/450 U/W series are miniaturized versions of the Murata CFU/CFWS lines.
These compact, highly selective characteristics are recommended for use in applications ranging from two-way radio to auxiliary filters in high class transceivers.
These ultra-miniature versions consume approximately 40% less volume while still offering the same high performance filter characteristics.
