## Products
- [MODEL 2227 Q\-MODULE](https://www.silicondesigns.com/product/inertial-and-reference/2227/): The Model 2227 Q\-Module is a low\-mass, low\-power MEMS inertial accelerometer, designed for inertial navigation and tilt applications requiring zero\-to\-medium frequency response\. 
- [SDI 1521 SURFACE MOUNT ACCELEROMETERS](https://www.silicondesigns.com/product/industrial-grade-surface-mount-accelerometers/1521/): The Model 1521 is SDI’s proven general\-purpose industrial surface\-mount accelerometer family\. Available in a broad range of acceleration levels and package options, it provides reliable DC measurement for industrial, test, monitoring, robotics, structural, aerospace, and defense applications\.
- [MODEL 1527 TACTICAL\-GRADE INERTIAL SURFACE MOUNT](https://www.silicondesigns.com/product/inertial-grade-surface-mount/1527/): ECCN 7A994 \- With an average bias repeatability better than 2 mg, the 1527 is SDI's tactical\-grade inertial measurement accelerometer\. Years of exhaustive R\&D have generated an exceptional MEMS accelerometer with superb Allan Variance, long term bias repeatability, scale factor stability, axis misalignment and vibration rectification error\.
- [SDI 1523 PRECISION INDUSTRIAL SURFACE MOUNT ACCELEROMETERS](https://www.silicondesigns.com/product/industrial-grade-surface-mount-accelerometers/1523/): The Model 1523 is the highest\-performing accelerometer in Silicon Designs’ industrial surface\-mount family\. It was developed for applications where temperature\-related changes in bias and scale factor represent a significant part of the measurement error budget\.
- [MODELS EB\-L \& EB\-J ANALOG TEST SETS](https://www.silicondesigns.com/product/accelerometer-accessories/eb-l-eb-j/): The Model EB\-J Test Set provides a convenient way to evaluate SDI surface\-mount accelerometers\. It includes a pre\-installed zero\-insertion\-force socket, configurable jumpers for supported accelerometer functions, and a 10\-pin connector with ribbon cable for connection to external test equipment\.
