Introduction
FM-broadcasting generally has high fidelity and a high S/N
ratio. In Europe and North America, there is a particularly
large number of FM-broadcasting stations. The performance
of FM-receivers is, therefore, greatly dependent on the
characteristics of the intermediate frequency filter
(selectivity, waveform symmetry, group delay time, etc.).
Murata's ceramic filter SFE10.7/SFT10.7 Series for FM-
receivers are monolithic type ceramic filters which use the
energy trapped thickness vibration-mode of the piezoelectric
ceramic.
Ceramic filters are compact and of simple structure, with
high selectivity, excellent temperature and environmental
characteristics, and favorable waveform symmetry. Because
of these excellent features,
Murata's ceramic filter has stable receiving performance.
In recent years, FM-receiver technology has progressed
rapidly;
¡Electronic
tuners have replaced mechanical tuners.
¡Tuners
have progressively been given higher selectivity and
better functions for car-radio receivers.
¡High
fidelity characteristics have rapidly improved for home
audio equipment.
¡One-chip,
non-adjustment ICs have been developed.
¡Compact
and low profile because of many chip components
used (e. g. for headphone audio).
¡Automatic
insertion technology for taped components has
progressed.
Various types of ceramic filters for FM receivers
(SFE10.7/SFT10.7 series) are available to meet the needs
of divers types of FM receivers.
!NOTICE
¡Matching
condition should be evaluated to perform stable
electrical characteristics which are specified.
¡Covering
filter with over coat, conditions, such as material of
resin cure temperature and so on be evaluated well.
¡Conformal
coating of filter is not acceptable due to unsealed
construction.
¡Filter
might be damaged when an excess stress will be
applied.
¡We
can no warrant against defects caused by any use of the
filter which deviates from the intended use as described in this
catalog. Please contact us for any other characteristics,
using conditions or application to the device which need to
be extremely reliable.

CERAMIC FILTERS
CERAFIL
®
is the Registered Trademark
of Murata's Ceramic Filters.
Chip Ceramic Filter
SFECV10.7
Series
Contributing to the Reduction of AM/FM IF Circuit
The chip CERAFIL
®
SFECV series is high performance filter.
Together with the PFWCC455 filter series for AM, the
SFECV10.7 filter series reduces the size of IF circuit in
AM/FM radios.
!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. The piezoelectric element is connected in the sandwich
shape by heat heat resistant substrates, thus it has
excellent mechanical strength, and it is suitable for
automatic mounting.
4. Various band-widths are available. Select a suitable type
in accordance with the desired selectivity.
5. Electrical characteristics are the same as conventional
