Ceramic Gyro
Outline
Ceramic Gyro is a miniature angular rate sensor having
a very simple construction that is made up of a single
piezoelectric ceramic column printed with electrodes.
Features
• Miniature size
• High-speed response
• SMD applicable to lead-free reflow soldering
Applications
• Image stabilizing system on camcorder, camera
and binocular
• Stability control of radio-controlled helicopter
• Input equipment (mouse etc.)

* Two ceramic gyro models in two specifications are
provided so that noise interference can be avoided.
When two gyro rate sensors are to be used within a
short distance, it is recommended to combine each
specification.

1) Since a residual carrier noise may be included in the output voltage (between Vref and Vout),
it is necessary to connect a low pass filter for higher harmonic component elimination.
2) A high pass filter is generally connected for eliminating the influence of output voltage fluctuation (by temperature, etc.) in stationary state.
3) It is recommended to ground the Vref terminal with a capacitance of 4.7μF to stabilize the
Vref output.
Before Using Ceramic Gyro
• When transporting or handling a sensor, be careful not to drop it or subject it to any other physical shock.
Failure to do so may lead to internal damage or deterioration of its characteristics.
• Avoid applying mounting voltages higher than the rating to the sensors pins. This will lead to overheating
or damage to the sensors.
• As sensors are not water resistant, cleaning should be avoided.
• When handling sensors, anti-electrostatic precautions must be taken.
