Procurement Notes

Verify the specific datasheet version for the 10M620J to confirm exact electrical tolerances and physical dimensions before integration. Confirm RoHS compliance status as required by project specifications. Ensure the axial lead spacing matches the target PCB footprint. Validate that the 495 mA DC current rating meets the operational requirements of the circuit design.

Selection Notes

Select this component when a fixed inductance of 620 nH is required for RF applications. The axial package is appropriate for through-hole assembly processes. Consider the 0.6-ohm DC resistance impact on circuit efficiency. The unshielded design may require careful layout consideration to minimize electromagnetic interference with adjacent components.

Part Context

The 10M620J belongs to Gowanda Electronics' standard RF inductor line, which includes various inductance values in the 10M series. These components are engineered for high-performance environments including aerospace and defense. The series offers both shielded and unshielded options with different core materials to suit specific frequency and stability requirements.

Replacement Considerations

Cross-reference with other Gowanda 10M series parts for similar inductance values if exact specifications vary. Verify compatibility with existing board layouts due to axial lead dimensions. Check alternative manufacturers for equivalent 620 nH RF inductors if supply constraints exist.
