Current Sense Transformers Procurement Notes

Verify the specific suffix configuration against official documentation to ensure correct packaging and termination style. Confirm that the 1:125 turns ratio aligns with system signal conditioning requirements. Check RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure PCB footprint matches the specified gull-wing terminal layout.

Current Sense Transformers Selection Notes

Select this component when a 50 A current rating and 1:125 transformation ratio are required. Consider the 7 mH inductance value for low-frequency response needs within the 20 kHz to 1 MHz operational band. Evaluate the physical size constraints against the 20.50 mm x 12.80 mm x 7.50 mm envelope. Compare primary resistance losses against thermal management capabilities in the target application.

Current Sense Transformers Part Context

This part belongs to the PAS6322 series of SMT current sense transformers from Pulse Electronics. The series is characterized by robust construction for demanding electrical environments. Variants within the family differ primarily in turns ratio and inductance values while maintaining similar form factors and current handling capabilities for consistent design integration.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 1:125 ratio, 50 A rating, and 7 mH inductance. Verify mechanical compatibility with the 20.50 mm x 12.80 mm footprint and gull-wing terminals. Cross-reference electrical parameters such as primary DCR and operating frequency range to ensure functional equivalence in the circuit.
