MPX12DP

Pressure Sensors Transducers Overview

The MPX12DP is a silicon piezoresistive differential pressure sensor from the MPX12 series, manufactured by NXP Semiconductors. It provides an accurate and linear voltage output directly proportional to applied pressure without internal temperature compensation. The device operates within a working pressure range of 1.45 psi (10 kPa) and features dual radial barbless ports with a size of 4.93 mm. Designed for through-hole mounting in a Unibody-4 package, it supports a maximum supply voltage of 3 V. The sensor functions reliably across an operating temperature range of -40°C to +125°C.

Pressure Sensors Transducers Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part is officially discontinued by the manufacturer. Confirm that the received unit matches the MPX12DP designation and package type. Check for any handling damage or contamination on the pins and ports before integration into circuit designs. Ensure compatibility with existing system voltage limits and thermal constraints.

Pressure Sensors Transducers Selection Notes

Select this component only when uncompensated pressure sensing is acceptable for the target application. Evaluate the need for external calibration due to the lack of integrated temperature compensation. Consider the through-hole mounting requirement and Unibody-4 package dimensions during PCB layout. Assess whether the 3 V maximum supply voltage aligns with the system power architecture.
