• Industrial control systems requiring galvanic isolation

Current Sensors Procurement Notes

Verify the specific suffix 'NPS' corresponds to the required through-hole package configuration and pinout. Confirm that the bidirectional current range of -85 A to 85 A aligns with the application's peak load requirements. Ensure the operating temperature range of -40°C to 105°C meets environmental specifications. Cross-reference the datasheet version date to confirm technical parameters have not been revised.

Current Sensors Selection Notes

Select this component when high accuracy and fast response are critical for current monitoring. The 25 A nominal rating suits moderate power applications, while the extended ±85 A range handles transient overloads. Consider the 4.75 V to 5.25 V supply requirement for compatibility with standard logic levels. Evaluate the 300 kHz bandwidth against the highest frequency components of the measured signal to prevent distortion.

Current Sensors Part Context

The LXS 25-NPS belongs to the LXS series of compact current sensors designed for space-constrained applications. This series integrates fluxgate-like performance into a small module format. It serves as a solution for designers needing isolated current feedback without the complexity of external compensation circuits. The part is distinct from unipolar variants by its ability to measure negative currents.
