Resonator
Piezoelectric Resonator (4 to 20 MHz)
FAR Family (C3 series M/N type)
■DESCRIPTION
The features of the C3 series (M,N Type) resonators are compact and high stability. They are f abricated on a
lithium tantalate (LitaO3) substrate, producing resonators with ultra compact and superior stability due to the
high electromechanical coupling coefficient of the material.
They include two loading capacitors inside and are housed in chip type of package f or surface mount. These
contribute saving mount space and reducing cost.
■FEATURES
• High stability (Overall frequency deviation; 0.10% max)
• Ultra small package
• Wide frequency range in 4 MHz to 20 MHz
• Suita ble for microcomputer cl ock
• Emboss-typed pack for automatic mounting
• Superior shock and vibration resistance, preventing damage during automatic mounting

■STANDARD FREQUENCY
Notes: • Fujitsu can also develop another frequency device besides standard devices within 4 MHz to 20 MHz.
• Regarding resonant resistance, maximum standard values are specified depending on frequency.
■NOTES ON USE
• Handle carefully.
• Solder heat resistance.
5 secon ds max. at +230°C (on PCB)
Recommended preheating is +150°C for one minute f or a v oiding giving e xtreme heat fluctuation to resonator .
• Avoid using resonator under condition of extreme temperature fluctuation.
• There is no specific direction in resonator mounting.
• Oscillation data must be considered in case that this resonator is used as microcomputer clock.
• Resonator is designed for reflow solder, not for flow solder.
