Fixed Inductors Procurement Notes

Verify the specific part number suffix to ensure compatibility with required shielding levels and current ratings. Confirm that the manufacturer documentation explicitly lists this exact model as a shielded or semi-shielded variant, as generic series data may not apply. Cross-reference the datasheet for precise thermal and electrical limits before integration.

Fixed Inductors Selection Notes

Select this component when a compact 5x4 mm footprint is required for power management tasks. Ensure the application demands a 47 µH value with ±20% tolerance. Verify that the circuit operates within the specified 800 mA current limits and requires the low-profile SMD form factor for PCB space constraints.

Fixed Inductors Part Context

This component belongs to the CHNR5040 series of surface-mount power inductors. The series offers various inductance values tailored for different power conversion needs. The 5040 package size provides a balance between current handling capability and board space efficiency for modern electronic designs.

Fixed Inductors Replacement Considerations

Direct substitutes include other 47 µH, 5x5x4 mm shielded wirewound inductors with comparable current ratings. Verify pinout compatibility and thermal characteristics when replacing.
