Fixed Inductors Procurement Notes

Verify the manufacturer datasheet for the specific lead time requirements associated with this part number. Confirm that the nonstandard package dimensions align with your PCB footprint constraints. Ensure the 3.6 A current rating meets the thermal and electrical demands of your target application environment before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a 22 µH inductance value is required alongside a 3.6 A current handling capability. The low DC resistance of 43.2 mΩ helps reduce conduction losses in power paths. Consider the shielded drum core design if EMI suppression is necessary within the circuit layout compared to unshielded alternatives.

Fixed Inductors Part Context

This part belongs to the RL-7500 series of high-current SMD power inductors from Renco Electronics. The series offers various inductance values and current ratings tailored for demanding power electronics. The RL-7500-3-220M specifically addresses needs for moderate inductance with significant current capacity in compact form factors.

Fixed Inductors Replacement Considerations

Cross-reference with other shielded drum core inductors offering 22 µH ±20% and at least 3.6 A rating. Verify physical package compatibility as the RL-7500 uses a nonstandard footprint. Check DCR specifications to ensure equivalent or lower resistive losses in the replacement component.
