Communication Ceramic Filters (LTM 455/450 U/W)

Direct communication ceramic filter is Murata CFUM/WM 455/450 compatible. Direct 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. Download complete (LTM 455/450) Communication Ceramic Filter Datasheet PDF (291KB).
