Ceramic Filters (CERAFIL
r
) for FM Receivers
CERAFIL
r
Small Chip Type SFECS Series
SFECS10M7 series for FM-receivers are small, high
performance and super thin (1.4mm) filters.
Piezoelectric element is connected in the sandwich
shape by ceramics substrate.
They have 1.4mm thickness and small mounting area.
(3.5x3.1mm)
New SFECS series and PFWCC(kHz filter for AM receiver)
enable customers to make AM/FM set so thin and small
sized.
I
Features
1. The filters are mountable by automatic placers.
2. They are slim, at only 1.4mm thickness, and have
a small mounting area (3.5x3.1mm) enabling
flexible PCB design.
3. Various bandwidths are available. Select a
suitable type in accordance with the desires
selectivity.
4. Operating temperature range :
-20 to +80 (degree C)
Storage temperature range :
-40 to +85 (degree C)
