Ceramic Resonators(SMD)
CCR Series
FEATURES
• The CCR series are thin-type ceramic chip resonators. Thick-
ness shear mode or 3rd over-tone thickness expansion mode
element are used for both the 4.0 to 11.0MHz band and the 16.0
to 50.0MHz band.
• Products with built-in loading capacitance have piezoelectric ele-
ments that are mounted onto a capacity-forming dielectric sub-
strate.
This eliminates the need for external capacitors, thus simplifying
circuit requirements.
• Optimization of the temperature characteristics of both the
piezoelectric element and dielectric materials has resulted in
stable oscillating frequency.
• Corresponds to reflow soldering. Moreover, it is possible to cor-
respond Pb-free soldering.(260°C,10sec. max.)
Packaging style is emboss taping.
• Setting or matching of oscillating frequency which correspond to
new models, application IC or custom IC are also available,
please contact TDK.
