Current Sensors Procurement Notes

Verify the specific suffix 'R' against official Tamura documentation to confirm reel packaging or variant status. Ensure the required supply voltage matches the 5V specification. Confirm that the 40A detection limit aligns with system requirements. Check RoHS3 compliance status if environmental regulations apply. Validate the through-hole mounting type against PCB layout constraints.

Current Sensors Selection Notes

Select this model when bidirectional AC/DC current sensing is required up to 40A. The open-loop design offers a balance between cost and performance for general applications. Consider the 100kHz bandwidth for high-frequency switching environments. The 5V supply requirement simplifies integration with standard logic levels. Ensure the thermal environment stays within the specified -30°C to 80°C range.
