Procurement Notes

Verify that the specific part number matches the required current rating and termination style. Confirm that the operating frequency range aligns with the application's signal requirements. Ensure that the physical dimensions fit within the designated enclosure space. Check for any specific handling instructions regarding the wire leads during assembly.

Selection Notes

Select this component when a 7 A primary current rating is required for non-invasive measurement. Consider the 1000:1 turns ratio for compatibility with downstream signal conditioning circuits. Evaluate the 38 Ohm secondary resistance against the burden resistor specifications. Ensure the free-hanging form factor is compatible with the mechanical layout constraints.

Part Context

This model belongs to the CR8400 series of current sense transformers. It shares design principles with other models in the family but differs in primary current rating and physical package. The series is characterized by high linearity and robust construction for industrial environments. This specific variant offers wire lead termination for flexible PCB or harness integration.

Replacement Considerations

Direct substitutes may include other CR Magnetics models with similar current ratings and ratios. Verify compatibility with existing circuit parameters before substitution. Cross-reference pinout and dimensional tolerances to ensure mechanical fit. Consult manufacturer documentation for updated equivalent part numbers.
