SFECV10M7 series for FM-receivers are monolithic type

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".
