Procurement Notes

Verify the specific suffix and reel quantity requirements with the manufacturer or authorized distributor before ordering. Confirm that the component meets the required AEC-Q200 standards for your specific application environment. Ensure compatibility with your PCB footprint and soldering profile, as manual soldering is generally not recommended for this SMD package.

Selection Notes

Select this component when a 30:1 isolation ratio and 15 A primary current handling are required in a compact surface-mount form factor. Consider the 500 µH maximum inductance and 320 mΩ secondary resistance for circuit matching. Verify that the 50 kHz to 1 MHz operational bandwidth aligns with your switching frequency needs.

Part Context

This part belongs to the ECSTA series of current sense transformers from Eaton Electronics. These components are engineered for precise current monitoring in power electronics. The series offers various turns ratios and current ratings to suit different power levels while maintaining small footprints suitable for modern dense PCB layouts.

Replacement Considerations

Check for direct substitutes within the Eaton ECSTA series with similar 30:1 ratios and 15 A ratings. Verify pinout compatibility and physical dimensions before replacing. Consult official Eaton documentation for approved alternative part numbers.
