... Due to its robust design with a metallic lid and monolithic integrated EMI-blocking capacitors and utilization of Silicon MEMS technology, the SMM310 shows high immunity to EMI (Electromagnetic Interference) and heat. The capped Chip-On-Board package solution contains the micromechanical sensor chip and an amplifier chip. ...
