Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure the correct inductance value and tolerance match the circuit requirements. Confirm that the package dimensions align with the PCB footprint design. Check for RoHS3 compliance documentation if environmental regulations apply to the final product assembly.

Fixed Inductors Selection Notes

Select this component based on the required 15 µH inductance and 4.5 A current rating. Ensure the 27 mΩ DC resistance meets the efficiency targets of the power stage. Consider the shielded design benefits for noise-sensitive environments compared to unshielded alternatives.

Fixed Inductors Part Context

This part belongs to the RL-7500 series of fixed inductors from Renco Electronics. The series includes various inductance values and current ratings tailored for different power management needs. The RL-7500-3-150M specifically addresses applications requiring moderate inductance with high current capacity in a compact surface-mount form factor.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include RL-7500-3-180M for higher inductance. Cross-brand replacements require matching the 15 µH value, 4.5 A current rating, and similar physical dimensions to ensure compatibility with existing PCB layouts.
