Composition
*
Centre Frequency (fo) is available in
the range from 450kHz to 470kHz.
The standard tolerance of fo is
±2kHz. For synthesizers and digital
indicators a tolerance of ±1kHz is
available.
*
The LP455JL series, with its two
directly coupled elements, realizes a
high degree of selectivity. The series
features excellent matching
characteristics for IFT.
