General Description
The SCA830-D06 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-D06 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-D06 is a part of Murata's digital accelerometer family and fully compatible with its multi axis accelerometers (SCA2100 series and SCA3100 series) and other single axis accelerometers (SCA800 series).

1) Typical ± values are ±3 sigma variation limits from validation test population. 2) Includes offset deviation from 0 g value including calibration error and drift over lifetime, temperature and supply voltage. 3) Includes offset deviation from 0 g value including calibration error and drift over lifetime. 4) Offset drift due to temperature. Value is a relative value and has not been centered to 0g. Error defined as maximum change of.
Offset in temperature range. Offset (max) - Offset (min). 100% tested in production. 5) Biggest change of output from RT value due temperature.
