Procurement Notes

Verify the specific ordering suffix to confirm material composition and regulatory status. The base part number may denote non-compliant variants, while the -RC suffix explicitly indicates RoHS compliance. Ensure the selected variant matches the required lead-free specifications for your manufacturing process. Cross-reference the datasheet for exact mechanical tolerances before finalizing procurement orders.

Selection Notes

Select this component based on the required 4 mH inductance value and 1.7 A current rating. Confirm that the through-hole package fits the available PCB footprint constraints. Evaluate the DC resistance impact on circuit efficiency if used in low-voltage applications. Ensure the operating temperature range aligns with the system's thermal environment requirements.
