High-Frequency Resonator
Piezoelectric Resonator
(24 to 40 MHz)
FAR Family (C4 Series L Type)
■
DESCRIPTION
The C4 series (L Type) resonators apply to the frequency range 24 to 60 MHz.
They are fabricated on a lithium niobate (LiNaO
3
) substrate, producing resonators with ultra compact and superior
stability due to the high electromechanical coupling coefficient of the material.
They use the third overtone resonance, so that they can oscilate at high frequency.
They include two loading capacitors inside and their package are chip type for surface mount. It contributes
saving space and reducing mount cost.
■
FEATURES
• High frequency (24 to 60 MHz)
• Surface mount package (SMT)
• Suitable for the source of microcomputer clock
• Emboss-typed pack for automatic mounting
• Superior shock and vibration resistance, preventing damage during automatic mounting

NOTES ON USE
• Handle carefully
• Solder under the following conditions.
5 seconds max. at 230
°
C (PCB)
Recommended preheating is 150
°
C for one minute in order not to apply extreme heat to the resonator.
• Avoid extreme fluctuations in temperature.
• There is no specific direction in resonator mounting.
• Oscillation data should be examined when used in oscillation circuit with micon or other ICs.
• This is for reflow solder, not for flow solder.
