LT10.7M Ceramic Filters for FM Receiver
(LT10.7M) Ceramic Filters
are Compatible Murata SFELF10M7
Preview
Token LT10.7M series are monolithic devices whichutilize
the energy-trapped thickness vibration-mode. This principle
of operation is based upon the fact that an excellent
resonating element with low spurious vibration can be
obtained by adhering to certain theoretical parameters of
design. These parameters include the physical dimensions
of the peizo element, the electrode pattern, and the associated
mass loading effect of the electrodes.
Token categorizes the LT 10.7 family according to rank of
center frequency. This ranking indicates that a given LT 10.7
will be marked with one of the colors listed in the following
chart and will exhibit the center frequency in Technical
Characteristics Table.
The LT10.7M offers three series: LT10.7M for FM Receiver (Compatible Murata SFELF10M7), LT10.7M A10
Insertion Loss 2.5±2.0 db ~ 4.5±2.0 db (Compatible Murata SFELF10M7 A10), and LT10.7M Wide Band-width
950 kHz at 20dB/Narrow Band-width 95 kHz at 20dB (Compatible Murata SFELF10M7 DBS Receiver).
LT10.7M Narrow Band-width series features stable low spurious and temperature characteristics. This series
is suitable for European car-audio or AM up conversion use that needs narrow band characteristics are stable.
LT10.7M Wide Band-width series are specified to make up conventional ceramic filters which wider band
characteristics not obtained.
Custom parts are available on request. Token will also produce devices outside these specifications to meet
specific customer requirements,
please contact our sales for more information.
Applications
- Change in center frequency is typically within ±30ppm/°C at -20°C to +80°C.
- Various band widths are available for applications in wide to narrow bands.
- Low loss, favorable waveform symmetry, and high selectivity.
- These miniature filters have high mechanical strength.
- Excellent shape factor of frequency response.
- Small dispersion and stable characteristics.
- Good waveform symmetry.
- High reliability.
