Fixed Inductors Procurement Notes

Verify the specific suffix 'ML' against official Bourns documentation to confirm terminal configuration and packaging details. Ensure that the selected variant matches the required thermal management capabilities for the intended operating environment. Cross-reference the datasheet for precise dimensional tolerances before finalizing the bill of materials.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0604 footprint with moderate current handling. Evaluate the 900 mA saturation current against peak load requirements. Consider the 190 mΩ resistance impact on efficiency. Verify compatibility with standard reflow soldering profiles for surface mount assembly.

Fixed Inductors Part Context

This part belongs to the SRR0604 series of shielded power inductors by Bourns Inc. The series offers various inductance values within the same physical envelope. These components are designed for applications demanding high reliability and low profile in portable or dense electronic systems.

Fixed Inductors Replacement Considerations

Direct substitutes include other SMD power inductors with identical 0604 dimensions, 22 µH nominal value, and comparable current ratings. Verify pinout compatibility and thermal performance before substitution.
