Common Mode Chokes Procurement Notes

Verify the manufacturer part number PA3747.146NL against official Pulse Electronics documentation to ensure authenticity. Confirm that the specific package dimensions and lead configurations match your PCB footprint requirements. Check for any recent Product Change Notifications (PCN) issued by the manufacturer regarding material or process updates. Ensure compliance with relevant safety standards required for your specific application environment before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a single-channel common mode choke is required for power line filtering with a 1 A current rating. The 9.1 mH inductance offers significant impedance at low frequencies suitable for EMI suppression. Consider the through-hole mounting style if surface-mount alternatives are not feasible. Verify that the 207 mOhm DC resistance aligns with your system's voltage drop constraints and thermal management capabilities.

Common Mode Chokes Part Context

This component belongs to the Pulse Electronics common mode choke family, specifically tailored for power line interference mitigation.
