Common Mode Chokes Procurement Notes

Verify the specific suffix 'NK' against official Schurter documentation to confirm material composition and compliance status. Ensure the selected variant matches the required lead-free or RoHS specifications for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the through-hole package dimensions align with your PCB footprint design before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a 12 A current rating and 6.8 mH inductance are required for single-phase noise suppression. Consider the radial lead configuration for through-hole assembly processes. Evaluate the unshielded design suitability against nearby sensitive circuitry. Verify that the operating temperature range meets the environmental conditions of the target application.

Common Mode Chokes Part Context

This component belongs to the Schurter DKIH series of common mode chokes. The series offers various inductance and current ratings for single-phase applications.
