Procurement Notes

Verify the specific suffix against official Gowanda documentation to confirm material composition and environmental compliance status. Confirm that the axial lead pitch matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the final assembly environment constraints before procurement.

Selection Notes

Select this component when unshielded axial inductors are required for aerospace or medical environments. The 1.2 µH value suits specific RF filtering needs. Verify that the 590 mA current rating meets circuit demands. Consider the lack of shielding if EMI sensitivity is a primary design constraint.

Part Context

This part belongs to Gowanda's line of high-performance molded unshielded RF coils. The manufacturer specializes in custom magnetics for critical industries including aerospace, defense, and medical sectors. These components are engineered for reliability under rigorous operational conditions.

Replacement Considerations

Cross-reference the 10M121KLF variant if lead-free compliance is mandatory. Verify electrical equivalence regarding inductance and current ratings before substituting with other axial wirewound inductors from different manufacturers.
