Radiation tested MEMS inertial accelerometers for spacecraft electronics testing

Silicon Designs has launched the Model 1527 Series, a family of miniature, radiation-tested, tactical-grade MEMS inertial accelerometers.

The series is provided in three standard full-scale acceleration ranges of ±10g, ±25g, and ±50g, respectively, and is expressly created to support various critical space electronics testing needs, including spacecraft satellites and CubeSats. Aso, their small bias and scale factor temperature coefficients, outstanding in-run bias stability, and zero cross-coupling by design make the series especially suited for those spacecraft electronics testing applications demanding low power consumption (+5VDC, 6.5mA), low noise, long-term measurement stability in -55C to +125C environments, and performance reliability under intermittent radiation exposures.

The rugged design combines a premium performance, tactical-grade MEMS inertial sense element with custom integrated circuit, internal temperature sensor, onboard sense amplifier and ±4V differential analog output stage. The MEMS inertial sense element and internal components are contained together within a lightweight, hermetically sealed, Nitrogen-damped, miniature, RoHS compliant, J-lead LCC-20 surface mount ceramic package (US Export Classification ECCN 7A994), weighing only 0.68g. Its compact and lightweight footprint enables easy accelerometer installation within space-constrained environments and minimises mass loading effects. Each accelerometer is also marked with a serial number for traceability on its top and bottom surfaces.
