Gyro Sensors/EWTS9P
MEMS Gyro Sensors
for Consumers
2 shafts in a package, SMD type
Type: EWTS9P□□□□
This sensor is an SMD-type two-axis integrated gyro sensorsr for consumer products.
The ultra-miniature body is achieved by integrating two MEMS silicon tuning forks on which a piezoelectric thin film
is directly formed, a bare IC chip, and other components into a single ceramic package.
In addition to analog output as a replacement for the existing model, digital output is also available with this series.
Therefore, this series is ideal for image stabilizers of DSCs and DVCs.

Gyro Sensors/EWTS9P
Safety Precautions (MEMS Gyro Sensors for Consumers/EWTS9P)
1. Soldering
(1) Thickness of Solder Paste(Recommendation) : 0.10 mm to 0.15 mm
(2) Flux
: Use non-corrosive rosin, and alcohol based solvent with little
chemical reaction
(3) Pre-heat
: Control the temperature on PWB to be under 180 °C and no
longer than 120 s
(4) Reflow Soldering condition
: The Maximum temperature on PWB under 260 °C, Soldering time
of the Maximum temperature within 10 s
(5) Atmospheric Temperature
: The atmospheric temperature should be under 300 °C
(6) Number of times it can be Reflow Soldered : 2 time as the limit
(7) Hand soldering
: Do not apply Hand soldering or correction of soldering
2. Washing
Since this sensor package is not sealed, do not apply any flux washing.
And at the set assembly process, please do not let oil etc. adhered because it may interfere with the sensor behavior.
3. Handling
(1) Handle with care. Do not drop or apply any strong impact to the sensor as it may degrade some performances.
(2) Static Electricity
Since CMOS IC is used, there is a possibility of static electricity destruction. Handle with care against static
electricity.
(3) Storage under the following condition should be avoided as it degrades the performance and solderability.
a) Relative humidity more than 85 %, or outside of storage temp. range.
b) Exposure to the direct rays of the sun.
c) Atmospheres of corrosive gas (CI2, H2S, NH3, NOX, SO2 etc.)
d) Long term storage of over 3 months after delivery
Do not store the package under severe load and stress..
4. Recommendation item on the circuit composition
(1) Place a chip capacitor (0.01 µF to 0.1 µF) near Vdd terminal across GND.
(2) Load of terminal OUTa and OUTb.
Load Resistor (OUTa & OUTb to GND) : 100 kΩ min. or none.
Load Capacitor (OUTa & OUTb to GND with series resistor 1kΩ) : 0.01 µF max.
(3) When the sensor signal goes to an A/D converter, use the same 3 V power supply both for the sensor and for
A/D converter.
(4) Misconnection
As misconnection causes a failure, do not reuse the sensor if once misconnected.
5. Caution of sensor layout
(1) Do not locate the sensor close to heat radiating objects such as power transistors. Since the sensor has a
little temp. drift by surrounding condition, carefully consider the location of the sensor.
(2) Do not locate two or more sensors on the same PWB because periodical drift of zero point output may occur
due to mutual interference by the vibration of each tuning fork of the sensor.
6. Caution of vibration from outside
To prevent the PWB’s (mounted sensor) from resonating with external vibration, please follow the instructions
below when designing PWB.
(1) Rigid glass epoxy circuit board is recommended. Locate the sensor near the screws which fix the circuit board.
(2) Place parts to avoid possible contacts with the sensor by external vibrations.
(3) Since the tuning fork may be damaged by the impact of cutting a mother board or a router, please check
carefully.
(4) This sensor has oscillators (tuning forks), which have some resonant frequencies. Since the sensor may cause a
malfunction by incoming frequencies similar to the sensor (41 kHz to 46 kHz), carefully check frequencies and
locations of DC/DC converters.
(5) Avoid screw loose of the circuit board.
(6) Conduct vibration tests and carefully check the condition of sensor when attached to the system. If the
location of the sensor is far from the screws of the circuit board, or the screws become loose, vibrations and
temperature change may degrade the performance.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
