LTM 455/450 U/W Filter 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.
