The <MMR933XA> is an advanced pressure sensor that is installed in smartphones, wearable devices and activity meters that are increasing in market size, and has been designed to deliver the same absolute pressure accuracy, effective pressure resolution and other performance characteristics as Mitsumi's existing product, the MMR931XA (3.0mm × 3.0mm), but with a minimized mounting area.
Mitsumi's proprietary packaging technology achieves the world's smallest class size of 2.0mm × 1.9mm, which contributes to a reduction in installation volume of devices that the sensors are installed in.
Mitsumi's proprietary packaging technology established for the world's smallest class package size.
Includes Mitsumi's AFE-IC for a high resolution up to 2.0Pa. (0.17m)
Corrections made to sensor fluctuations and temperature characteristics before shipped from the factory.
