Current Sensors Procurement Notes

Verify the specific suffix 'PFF' corresponds to the required lead form factor for your PCB footprint. Confirm that the bidirectional sensing capability aligns with your application's current direction requirements. Ensure thermal management strategies account for the internal conductor resistance during peak load conditions.

Current Sensors Selection Notes

Select this component when bidirectional current sensing is required within the 100A range. Compare sensitivity options against your ADC resolution needs; the 20mV/A output may require amplification for low-current precision. Evaluate the CB package dimensions against available board space constraints.
