Procurement Notes
Verify the specific suffix against official documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the procurement channel provides valid RoHS compliance certificates matching the component's environmental standards. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and correct identification before finalizing orders.
Selection Notes
Select this component when a 12.7 µH inductance value is required for power management circuits. Evaluate the 1.21 A saturation current limit to ensure it meets the peak current demands of the application. Consider the 0.0828 Ω DC resistance for efficiency calculations and thermal management requirements in the target system design.
Part Context
This component belongs to the Eaton VERSA-PAC family, which includes configurable inductors and transformers. The series is engineered for high-density power electronics, offering standardized footprints and electrical characteristics suitable for modern switching power supplies and industrial control systems requiring reliable magnetic components.
Replacement Considerations
Consult Eaton technical resources for verified substitute part numbers. Do not assume functional equivalence with generic inductors lacking identical saturation current ratings or core material specifications.
