Common Mode Chokes Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may update pinout or mechanical tolerances over time. Confirm that the through-hole footprint matches your PCB design constraints. Ensure the selected component meets the required thermal management standards for your operating environment, specifically regarding the 105°C maximum rating. Cross-reference the 80 mΩ DCR specification against your circuit's voltage drop requirements.

Common Mode Chokes Selection Notes

Select this component when designing power inputs that require significant common mode noise attenuation without introducing excessive resistive loss. The 620 µH inductance value offers effective filtering for typical switching frequencies found in industrial power supplies. Consider the 1.7 A current rating to ensure adequate headroom for peak load conditions. The through-hole construction provides mechanical stability suitable for environments with potential vibration.
