Ceramic IF filters  

  These are ceramic IF filters used in FM tuners.

The centre frequency of ceramic filters varies quite a lot, so these filters are selected. For optimum performance all filters in the tuner should have the same centre frequency.

For tuners with analogue tuning, any of the centre frequencies will work. For tuners will PLL (digital) tuning, you need the centre frequency the tuner is set-up for. This is often 10.7MHz, but not always - check the service manual of the tuner. The tuner will not work correctly with narrow filters of the "wrong" frequency.

For low distortion use wide-band filters. For good selectivity choose narrow bandwidth.
