ceramic filters for communication - ltm455eu

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.

features

  • frequency range: 455 khz / 450 khz.
  • murata cfum/wm 455/450 compatible.
