| SHOULDER SPECIFICATION Item: Type: Ceramic Filter LTS...W Optional SHOULDER LTS...W Scope This specification shall cover the characteristics of the XT...MB Ceramic Filter. Ceramic Filters LTM 455/450W Series are miniaturized versions of the 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 characteristics.
