Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
CERAFILr MHz SMD Type SFECF10M7 Series
SFECF10M7 series for FM-receivers are small, high
performance and super thin (1.4mm max.) filters.
Piezoelectric element is connected in the sandwich
shape by ceramics substrate.
They have 1.4mm max. thickness and small mounting area.
(3.45x3.1mm)
SFECF series and CDSCB series (MHz Discriminator)
enable customers to make VICS/RKE/TPMS set so thin and
small sized.
■ Features
1. The filters are mountable by automatic placers.
2. They are slim, at only 1.4mm max. thickness, and
have a small mounting area (3.45x3.1mm) enabling
flexible PCB design.
3. Various bandwidths are available. Select a
suitable type in accordance with the desired
selectivity.
4. Operating temperature range: -20 to +80 (degrees C)
Storage temperature range: -40 to +85 (degrees C)
