Fixed Inductors Procurement Notes

Verify the complete part number against official Samsung Electro-Mechanics documentation to ensure correct suffix identification. Confirm that the specific ordering suffix matches the required packaging format and tolerance specifications. Cross-reference the manufacturer's latest datasheet to validate compliance with RoHS3 standards and environmental regulations before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact 1616 footprint is required alongside high current handling exceeding 12 Amperes. The low DC resistance makes it suitable for efficiency-critical designs where thermal management is constrained. Ensure the target application frequency aligns with the 470 nH value and that the operating environment stays within the specified -40°C to +125°C range.

Fixed Inductors Part Context

This component belongs to the CIGW series of power inductors manufactured by Samsung Electro-Mechanics. The series utilizes metal composite technology to achieve high performance in small surface-mount packages. These inductors are engineered for modern electronics requiring reliable energy storage in tight spatial constraints.

Fixed Inductors Replacement Considerations

Consult official substitution guides for compatible alternatives within the same series or package size. Verify that any substitute maintains equivalent saturation current and DC resistance ratings to prevent circuit performance degradation.
