DESCRIPTION
The features of the C3 series (M,N Type) resonators are compact and high stability. They are fabricated on a
lithium tantalate (LitaO
3
) 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 for surface mount. These
contribute saving mount space and reducing cost.

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.
s
NOTES ON USE
• Handle carefully.
• Solder heat resistance.
5 seconds max. at +230°C (on PCB)
Recommended preheating is +150°C for one minute for avoiding giving extreme 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.
