LT 455/450 U/W are 4-element and 6-element devices connected in ladder form. These highly selective filters are designed
to address the G.D.T. characteristics required in digital communications.
The excellent G.D.T. characteristics allow these filters to be utilized
in areas such as the mobile cellular markets as well as a variety
of stereo applications. (Also available in 450kHz version.) | LT 455/450 U/W for Communication ( Murata CF, SF series Compatible ) | 455 kHz / 450 kHz |
