General Description
The SCA830-D07 is a single axis inclinometer component based on Murata's 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.
The SCA830-D07 is designed, manufactured and tested for high stability, reliability and quality requirements of
automotive applications. The inclinometer has an extremely stable output over wide ranges of temperature, humidity
and mechanical noise. The component is qualified to the AEC-Q100 standard and has several advanced self
diagnostics features. The DFL housing is suitable for SMD mounting and the component is compatible with the RoHS
and ELV directives.
The SCA830-D07 is a part of Murata's digital accelerometer family and fully compatible with its 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)
After mounting of ECU the application and after offset zero-setting at room temperature. Relevant offset failure due
to temperature dependency of offset as well as aging over lifetime
D)
Includes offset deviation from 0g value including calibration error and drift over lifetime.
E)
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.
F)
Biggest change of output from RT value due temperature.
