Current Sensors Procurement Notes

Verify the specific suffix '1100' against official LEM datasheets to confirm exact primary current rating and pin configuration. Ensure compatibility with the specified 4.5V–5.5V supply range and 4.444mV/A sensitivity for your circuit design. Cross-reference package type and mounting requirements with system constraints before ordering.

Current Sensors Selection Notes

Select this component when high-speed response (3.5µs) and galvanic isolation are required for mixed-signal environments. The open-loop architecture offers cost-effective solutions for general-purpose current sensing where extreme precision may not be critical compared to closed-loop alternatives.

Current Sensors Part Context

This model belongs to the HO-P series, which represents LEM's standard open-loop current transducers. These devices are widely used in industrial automation and power conversion applications due to their robust construction and reliable performance in measuring electrical currents across various frequencies.

Current Sensors Replacement Considerations

Check LEM documentation for direct substitutes within the HO-P series or LT-series if different accuracy levels are needed. Verify that alternative models match the 4.5V–5.5V supply requirement and 4.444mV/A sensitivity to ensure functional equivalence.
