MODEL 3031 Accelerometer
SMD Accelerometer
Miniature DC Response
Piezoresistive MEMS
10,000g Over-Range Protection
DESCRIPTION
The Model 3031
is a piezoresistive SMD
accelerometer designed for demanding high
volume applications. The accelerometer is ideal
for applications requiring a miniature light weight
accelerometer with outstanding performance.
The model 3031 incorporates a 2nd generation
MEMS sensing element providing superior long-
term stability. The accelerometer provides a
millivolt output
signal and
features
mechanical
overload stops
that provide
shock
protection to
10,000g.
For non-
surface mount
accelerometers
please see Models
3022, 3028, 3052 or
3058.

Notes
1. The frequency response is defined as the range of frequencies over
which the device sensitivity is within ±5% of the DC value.
2. Output voltage increases for positive acceleration; output voltage
decreases for negative acceleration.
3. Best Fit Straight Line.
4. 10 Hz to 1 kHz.
