SFELF10M7 series for FM-receivers are monolithic type ceramic filters that use the thickness expander mode of the piezoelectric ceramic. As part of the environment protection program, the solder for terminal plating and terminal-element connection inside of the ceramic filter contain no lead (Pb).Features1. These miniature filters have high mechanical strength.2. Low loss, favorable waveform symmetry, and high selectivity.3. Various bandwidths are available for applications in wide to narrow bands.4. Small dispersion and stable characteristics.5. Change in center frequency is typically within ±30ppm/°C at -20 to +80°C.6. High reliability.
