NPA-300M-02WG

Pressure Sensors Transducers Overview

The NPA-300M-02WG is a board-mount pressure sensor from the NPA-700 series by Amphenol Advanced Sensors. It features an analog voltage output and operates with a supply voltage of 3.28V to 3.32V. The device measures differential pressure with a working range of 2 inches H2O (approximately 0.5 kPa) and a maximum pressure of 5.06 PSI (34.88 kPa). It utilizes a 14-SOIC package with top ports and offers temperature compensation. The sensor functions within a temperature range of -40°C to 125°C and provides an accuracy of ±2.5%.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix designation to ensure compatibility with required port styles and electrical characteristics, as variations exist within the NPA series. Confirm that the 3.3V excitation requirement aligns with the target circuit design. Check moisture sensitivity levels and reflow soldering profiles during assembly planning to prevent component damage. Ensure the selected variant matches the exact pressure range and accuracy needs for the application.

Pressure Sensors Transducers Selection Notes

Select this model when low-pressure differential measurement is required in space-constrained designs. The SOIC-14 package facilitates automated surface mount assembly. Consider the ±2.5% accuracy specification against application tolerances. Verify that the 2-inch H2O range suits the expected operating pressures. Evaluate the need for temperature compensation if the environment experiences significant thermal fluctuations.
