AVSensors CHT-SM5651 is a direct replacement for Silicon Microstructure Discontinued SMI 5651 Sensor

We are excited to announce the introduction of our CHT-SM5651 Series Pressure Sensor, a 0.600 DIP eight (8) pin Ceramic Hybrid Technology (CHT) package with high level mV output supporting 0.15, 0.30, 0.80 and 1.5 PSI ranges. The CHT-SM5651 series is powered using a constant current and when configured as in the Application Note, the integrated gain set resistor will ensure 2% field interchangeability. The CHT-SM5651 series superior die performance, coupled with rugged ceramic substrate ensures long term stability with superior temperature performance over a wide operating range.

Some of the key features of the CHT-SM5651 Series Pressure Sensor include:
