Silicon Designs introduces the Model 1527 series, a series of radiation-tested miniature tactical-grade MEMS accelerometers. The family offers three full-scale acceleration ranges—±10 g, ±25 g, and ±50 g—and is designed to support a variety of critical space electronics test requirements, including the rigors of spacecraft, satellites, and CubeSats.
Additionally, the family's small zero bias and scale factor temperature coefficients, excellent operating bias stability, and zero cross-coupling make it ideal for spacecraft electronics test applications that require low power consumption (+5 VDC, 6.5 mA), low noise, long-term measurement stability from –55°C to +125°C, and performance reliability under intermittent radiation exposure.
The rugged design of the Model 1527 family combines a tactical-grade MEMS inertial sensing element with a custom integrated circuit (ASIC), internal temperature sensor, on-board sense amplifier, and ±4V differential analog output stage. The MEMS inertial sensing element and internal components are housed in a lightweight, hermetically sealed, nitrogen damped, miniature, RoHS compliant J-lead LCC-20 surface mount ceramic package weighing 0.68 grams (US export classification ECCN 7A994).
The compact and lightweight package area of the Type 1527 family allows easy integration of MEMS accelerometers in space-constrained environments and minimizes mass loading effects. Each Model 1527 Series MEMS accelerometer is marked with a serial number for traceability on the top and bottom surfaces.
All Silicon Designs Model 1527 Series tactical-grade MEMS accelerometers are designed, manufactured, performance verified and calibrated in-house at the company's global corporate headquarters and R&D center outside Seattle, Washington. Product performance documentation is provided upon shipment and includes residuals, thermal sensor model, acceleration model, bias, scale factor, linearity, operating current and frequency response data.
