Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct tolerance and packaging specifications. Confirm that the requested quantity aligns with the standard reel size of 2,000 pieces per order. Ensure compliance with RoHS3 standards and check lead times as availability may vary by region.

Selection Notes

Select this component when a 430 nH inductance value is required for space-constrained designs. Consider the 470 mA current rating and 1.15 Ohm DCR for power loss calculations. The unshielded nature requires layout consideration to minimize electromagnetic interference coupling with nearby traces.

Part Context

This part belongs to the 1008CS series of wire-wound chip inductors from Delta Electronics. The series offers various inductance values within the 1008 case size, utilizing ceramic cores for stability. This specific model represents a mid-range inductance option within the family, balancing size and electrical performance.

Replacement Considerations

Direct substitutes include other manufacturers' 1008-sized unshielded wirewound inductors with 430 nH nominal value. Verify matching DCR, current rating, and self-resonant frequency before substitution. Cross-reference with Delta's own variants like 1008CS-431EGTS if shielding or different tolerances are acceptable.
