Current Sensors Procurement Notes

Verify the specific manufacturing lot date code against project requirements to ensure component freshness. Confirm that the open-loop architecture aligns with the system's isolation and accuracy needs. Check for any recent product change notifications from Tamura regarding material or process updates. Ensure the +5V supply rail stability meets the sensor's operational voltage range during procurement planning.

Current Sensors Selection Notes

Select this model when a compact board-mount solution with integrated busbars is required for currents up to 21A. The 1µs response time makes it suitable for applications demanding fast fault detection. Consider the ±1% linearity specification for systems requiring high measurement fidelity without external calibration. The open-loop design offers a cost-effective alternative to closed-loop sensors for non-isolated primary side measurements.
