Procurement Notes

Verify the specific suffix against official Eaton documentation to confirm package type and tape/reel specifications. Ensure the procurement channel provides valid RoHS3 compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to prevent counterfeit components. Confirm that the delivered units match the exact VERSA-PAC series designation required for thermal and electrical compatibility.

Selection Notes

Select this component when designing isolated SMPS architectures requiring a 7.63 µH inductance value. Evaluate the 1.7 A continuous current rating against peak load requirements to ensure adequate margin. Consider the 71.1 mΩ DC resistance impact on overall system efficiency. Verify that the surface-mount footprint aligns with existing PCB silkscreen and copper pad designs.
