Fixed Inductors Procurement Notes
Verify the specific RoHS3 compliance status and moisture sensitivity level (MSL 1) against the latest manufacturer datasheet before procurement. Confirm that the nonstandard package dimensions align with your PCB footprint requirements. Ensure the 2.2 A current rating meets the thermal and electrical demands of your target circuit design.
Fixed Inductors Selection Notes
Select this component when a shielded, high-current inductor is required for space-constrained designs. The 120 µH value suits moderate frequency filtering needs. Consider the 165 mΩ resistance for efficiency calculations. Verify availability of cut tape packaging if manual or small-batch reflow soldering is planned.
Fixed Inductors Part Context
This part belongs to the RL-7500 series of shielded high current SMD power inductors from Renco Electronics. The series offers various inductance values and current ratings. The '4' suffix typically denotes specific physical dimensions within the family, while '121M' indicates the 120 µH value.
Fixed Inductors Replacement Considerations
Direct substitutes are not explicitly confirmed in public documentation. Evaluate other RL-7500 variants like RL-7500-4-151M only if higher inductance is acceptable. Cross-reference pinout and thermal characteristics carefully when considering alternative manufacturers.
