Current Sensors Procurement Notes

Verify that the specific part number matches the required nominal current rating of 100A and the M2 series designation. Confirm that the application environment stays within the specified -40°C to 85°C temperature range. Ensure the power supply voltage aligns with the ±12V to ±15V operational limits. Check that the load resistance conditions do not exceed the 25Ω threshold if utilizing the maximum 160A current capacity. Validate compatibility with unidirectional circuit topologies before final procurement.

Current Sensors Selection Notes

Select this component when high accuracy and linearity are critical for unidirectional current sensing in general electronics. The closed-loop architecture offers superior performance compared to open-loop alternatives, particularly regarding dv/dt improvement. Consider the 500ns response time for applications demanding rapid signal processing. Ensure the physical weight of approximately 26g fits within the mechanical constraints of the target assembly.

Current Sensors Part Context

This model belongs to the S23P family of current sensors from Tamura. It serves as a succession model to previous iterations, offering enhanced performance metrics. The S23P series is characterized by its compact design and suitability for board-mount installations. This specific variant integrates a built-in bus-bar feature, simplifying installation in high-current environments while maintaining electrical isolation standards.

Current Sensors Replacement Considerations

Tamura recommends the S23P50/100D15M2 as a direct succession model for older variants within the S23P series. Verify pinout compatibility, specifically identifying terminals for Vcc (+/-) and Output. Ensure the replacement maintains the same unidirectional functionality and closed-loop operation requirements.
