• General-purpose signal processing

Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical tolerances and thermal characteristics before integration. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly. Cross-reference part numbers to distinguish between shielded and unshielded variants within the same series, as performance differs significantly based on magnetic shielding presence.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to minimize cost or size while maintaining moderate current ratings. The 47 µH value suits intermediate frequency switching applications. Consider the 110 mOhm DCR for efficiency calculations in low-voltage power paths. The non-standard package dimensions require careful PCB footprint verification against mechanical clearance constraints.

Fixed Inductors Part Context

This part belongs to the HDC450 series of Hi-Profile SMD Drum Core Inductors. The series offers various inductance values with consistent physical footprints. The 'MTR' suffix typically indicates reel packaging for automated surface-mount placement. HALO Electronics manufactures these components for industrial and commercial electronic equipment requiring reliable passive magnetic elements.

Fixed Inductors Replacement Considerations

Direct substitutes include other 47 µH unshielded drum core inductors with similar current ratings (approx. 3.8 A) and DCR (approx. 110 mOhms). Verify that replacement parts match the 13.05 mm x 9.4 mm x 11.5 mm envelope. Shielded alternatives may require derating due to different thermal dissipation characteristics.
