Ceramic Resonators(Lead)
FCR Series
FEATURES
The FCR series are small leaded ceramic resonators that used
thickness shear mode or 3rd over tone thickness mode element
of piezo ceramics with both 3.45 to 10.0MHz and 16.0 to
50.0MHz.
The products has a function of loading capacitance so you don't
need external capacitors. You can design a simplifying circuit
and cut down mounting costs.
Optimization of the temperature characteristics of both the
piezoelectric element and loading capacitance has resulted in
stable oscillating frequency.
Ammo packing is available for various automatic insert machine
(1500pieces/box). Short lead type and L-bend lead type are also
available, please contact TDK.
Setting or matching of oscillating circuit condition which
correspond to new models IC, application IC or custom IC are
available, please contact TDK.
The products don’t contain Lead at solder of internal joint and
solder plating of lead wire. You can use both Pb free solder (Sn-
3Ag-0.5Cu) and Sn-Pb eutectic solder on your production.
