Fixed Inductors Procurement Notes

Verify that the specific part number PM2110-3R9M-RC matches the required 3.9 µH inductance and 15.1 A current rating for your design. Confirm compliance with RoHS directives and lead-free status as indicated by the suffix. Ensure the operating environment stays within the specified -55°C to +105°C range to maintain performance reliability.

Fixed Inductors Selection Notes

Select this component when a high-current, unshielded toroidal inductor is required for surface-mount applications. The 4 mΩ DC resistance and 15.1 A rating make it suitable for power delivery paths where saturation current is critical. Consider the 14.48 mm profile for board space constraints compared to shielded alternatives.

Fixed Inductors Part Context

This component belongs to the Bourns PM2110 series of fixed surface-mount power inductors. The series offers various inductance values with similar physical dimensions and core constructions. The 'M' suffix typically denotes the ±20% tolerance, while 'RC' indicates RoHS compliance and lead-free termination materials consistent with modern environmental standards.

Fixed Inductors Replacement Considerations

Cross-reference other PM2110 series variants for different inductance values if electrical parameters differ. Verify that substitute components match the 14.48 mm height and 15.1 A current rating to ensure mechanical and thermal compatibility without redesigning the footprint.
