Fixed Inductors Procurement Notes

Verify the specific suffix 'HP' against official Sumida documentation to confirm high-performance specifications. Ensure the ordered part matches the required 15 µH value and 2 A current rating. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component for applications requiring compact shielding and moderate current handling. The 8x8 mm footprint offers a balance between size and saturation current. Evaluate the 75 mOhms DCR against system efficiency requirements. Consider the ±30% tolerance when designing precise filter cutoff frequencies.

Fixed Inductors Part Context

This model belongs to the CDRH series of SMD power inductors. It utilizes a unique drum-shaped ferrite core wrapped with wire, providing superior magnetic shielding compared to open coil designs. The series is designed for modern electronics demanding reduced component height and improved EMI performance.

Fixed Inductors Replacement Considerations

Direct substitutes include other Sumida CDRH8D28 variants with matching electrical parameters. Cross-reference dimensions and pinout compatibility when considering alternative manufacturers. Verify that replacement parts meet the same thermal and current saturation requirements.
