Procurement Notes

Verify the specific suffix and packaging configuration against the official Eaton datasheet before ordering. Confirm that the required quantity aligns with the manufacturer's minimum order requirements and reel specifications. Ensure compatibility with the intended soldering profile, as manual hand soldering is generally not recommended for this component type.

Selection Notes

Select this component when a 30:1 isolation ratio and 7 A primary current capacity are required for high-frequency current monitoring. The AEC-Q200 qualification makes it suitable for automotive environments requiring extended temperature stability. Compare secondary resistance and inductance values against circuit simulation requirements to ensure accurate signal fidelity at the target switching frequency.

Part Context
