Ceramic Filters (CERAFILr) for FM Receivers
CERAFILr Chip Type SFECV Series
6.9±0.3

SFECV10M7 series for FM-receivers are monolithic type
1.2±0.5

ceramic filters which utilize the energy trapped
thickness vibration-mode of the piezoelectric ceramic.
By taking advantage of the very low profile, new SFECV
series and PFWCC(kHz filter for AM receiver) enable
costomers to make AM/FM set so thin, and it can be of
help to the total chip circuit.

■ Features
1. Super-thin. Only 1.5mm. The most suitable ceramic
filter available for thinning substrates.
2. Heat resistant. Reflow soldering can be performed
because of its excellent heat resistance.
3. Piezoelectric element is connected in the
sandwich shape by heat resistant substrate, thus
it has excellent mechanical strength, and it is
suitable for automatic mounting.

4. Various bandwidths are available. Select a
suitable type in accordance with the desired
selectivity.
5. Electrical characteristics are the same as
conventional "CERAFIL".
■ Applications
1. Small, thin radios
2. Automotive radios
