DESCRIPTION
The Model 3031 is a piezoresistive silicon accelerometer in a
surface mount package. It is intended for high volume appli-
cations where small size, light weight, and low cost are
required.
This accelerometer consists of a micro machined silicon
mass suspended by multiple beams from a silicon frame.
Piezoresistors located in the beams change their resistance as
the motion of the suspended mass changes the strain in the
beams.
Silicon caps on the top and bottom of the device are
added to provide over-range stops. This design provides for a
very low profile, high shock resistance, durability and built-in
damping over a wide usable bandwidth.
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. Percentage values are with external compensation.
5. Compensated temperature range: 0-50°C in reference to 25°C.
6. 10 Hz to 1 kHz.
7. 20X or 2000g, whichever is less.
8. Solder on pads is 62% Tin, 36% Lead, 2% Silver. Maximum allowable
temperature during mounting is 220°C for 1 minute. Contact factory if a
higher mounting temperature will be used.
