General Description
SCA3100-D04 is a high performance three axis accelerometer component based on Murata capacitive 3D-MEMS
technology. The component integrates high accuracy micromechanical acceleration sensing together with a flexible
SPI digital interface. Dual Flat Lead (DFL) housing guarantees reliable operation over product lifetime.
SCA3100-D04 is designed, manufactured and tested for high stability, reliability and quality requirements of
automotive applications. The accelerometer has extremely stable output over wide range of temperature, humidity and
vibration. The component is qualified against AEC-Q100 standard and has several advanced self diagnostics features.
The DFL housing is suitable for SMD mounting and the component is compatible with RoHS and ELV directives.
SCA3100-D04 is a part of Murata digital accelerometer family and fully compatible with single axis accelerometers
(SCA800 series) and other multi axis accelerometers (SCA2100 series and SCA3100 series).

Typical ± values are ±3 sigma variation limits from validation test population.
B)
Includes offset deviation from 0g value including calibration error and drift over lifetime, temperature and
supply voltage.
C)
Includes offset deviation from 0g value including calibration error and drift over lifetime.
D)
Offset drift due to temperature. Value is a relative value and has been centered to zero. Error defined as maximum change
of offset in temperature range. Offset (max)-Offset Min). 100% tested in production.
E)
Biggest change of output from RT value due temperature.
