NPA-300B-05WG

Pressure Sensors Transducers Overview

The NPA-300B-05WG is a gauge pressure sensor from the NPA-300 series by Amphenol Advanced Sensors. It features an analog voltage output ranging from 0.5V to 3V with a supply voltage of 3.135V to 3.465V. The device has a working pressure of 0.18 PSI (1.25 kPa) and a maximum pressure of 60 PSI (413.69 kPa). Accuracy is ±1.5%. It uses a 14-SOIC package with top ports, operates between -40°C and 125°C, and includes amplified output and temperature compensation.

Pressure Sensors Transducers Feature Summary

• Low-flow air filtration monitoring

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'W' indicates the 0.18 PSI range variant against official datasheets. Confirm RoHS compliance status and MSL level 5A handling requirements during assembly. Ensure supply voltage matches the 3.135V to 3.465V specification to avoid output saturation or non-linearity errors in final integration.

Pressure Sensors Transducers Selection Notes

Select this model for applications requiring low-pressure gauge measurement with high thermal stability. The 14-SOIC form factor supports automated surface mount assembly. Verify port configuration compatibility with tubing dimensions prior to PCB layout. Consider the ±1.5% accuracy limit for precision-critical calibration needs.

Pressure Sensors Transducers Part Context

Part of the NPA-300 MEMS pressure sensor family designed for board-level integration. Offers a compact solution replacing discrete sensor assemblies. Provides factory-calibrated analog output suitable for microcontroller ADC inputs without external signal conditioning circuits.

Pressure Sensors Transducers Replacement Considerations

NPA-300B-05GD offers similar specifications with potential pinout or packaging variations. NPA-500B-05WG provides identical pressure range but operates at 5V supply levels. Cross-reference mechanical dimensions and electrical characteristics before substitution.
