LTM 455/450 Ceramic Filters Ceramic Filters for Communication Ceramic Filter for Communication (Murata CFUM/WM 455/450 Compatible) Preview 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. TOKEN
