Frequently Asked Questions
What measurement range and supply voltage does the SCA3100-D04 support for automotive stability applications?
The SCA3100-D04 provides a ±2g full-scale measurement range suitable for tilt, inclination, and low-acceleration automotive sensing. It operates from a 3V to 3.6V supply, compatible with 3.3V automotive microcontroller systems. Its AEC-Q100 qualification confirms it has been validated for the temperature cycling, humidity, and vibration stresses of automotive electronic control units.
How does the AEC-Q100 rating of the SCA3100-D04 differentiate it from commercial-grade accelerometers?
AEC-Q100 qualification on the SCA3100-D04 means it has undergone automotive reliability testing including temperature cycling from -40°C to +85°C or higher, electrostatic discharge robustness, and extended burn-in testing. Commercial-grade accelerometers without this qualification are only verified under benign conditions and may exhibit higher failure rates in automotive under-hood or exterior environments where temperature swings and vibration are severe.
What digital interface does the SCA3100-D04 use and how does it simplify system integration?
The SCA3100-D04 uses an SPI digital interface to output 3-axis acceleration data directly to a host microcontroller, eliminating the need for an external ADC. SPI communication allows fast data rates and daisy-chaining with other peripherals on the same bus. The digital output also avoids analog signal integrity issues like noise pickup on long traces, simplifying PCB layout in automotive and industrial environments.
What PCB footprint does the SCA3100-D04 require and which assembly process is compatible?
The SCA3100-D04 occupies an 8.6mm × 7.6mm surface mount footprint with a body height of 3.3mm, compatible with standard SMT reflow assembly processes. Its rectangular SMD package supports automated pick-and-place placement and solder paste reflow, making it suitable for high-volume automotive and industrial PCB production without special tooling or through-hole assembly requirements.
