Silicon Designs unveils MEMS inertial accelerometers for spacecraft electronics testing

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

Offered in three standard full-scale acceleration ranges, of ±10 g, ±25 g, and ±50 g, respectively, the Series is designed to support a variety of critical space electronics testing requirements, including those of spacecraft, satellites, and CubeSats. In addition, their small bias and scale factor temperature coefficients, excellent in-run bias stability, and zero cross-coupling by design make the series well-suited for those spacecraft electronics testing applications requiring low power consumption (+5 VDC, 6.5 mA), low noise, long-term measurement stability in -55°C to +125°C environments, and performance reliability under intermittent radiation exposures.

The rugged design of the Model 1527 Series combines a premium performance, tactical-grade MEMS inertial sense element, together with a custom integrated circuit, internal temperature sensor, onboard sense amplifier and ±4V differential analogue output stage.

Both the MEMS inertial sense element and internal components are housed together within a lightweight, hermetically sealed, Nitrogen damped, miniature, RoHS compliant, J-lead LCC-20 surface mount ceramic package (U.S. Export Classification ECCN 7A994), weighing just 0.68 gram. Its compact and lightweight footprint allows for ease of accelerometer installation within space-constrained environments, as well as the minimization of mass loading effects.

Each Model 1527 Series accelerometer is also marked with a serial number for traceability on both its top and bottom surfaces.

In addition, all Model 1527 Series tactical-grade MEMS inertial accelerometers are designed, manufactured, performance-verified, and calibrated in-house at the company's own global corporate headquarters and R&D centre, located just outside of Seattle, Washington, USA.

Product performance documentation is also supplied at the time of shipment, including residuals, thermal sensor model, acceleration model, bias, scale factor, linearity, operating current, and frequency response data.
