• Utilizes a robust through-hole construction for secure PCB attachment
• Engineered with ferrite core technology to maintain performance across operating temperatures

Common Mode Chokes Applications

• Power supply input filtering
• Signal line noise suppression
• EMI reduction in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific package dimensions and lead configuration against the official datasheet before integration. Confirm that the 1 A current rating and 410 mOhm DCR meet the circuit requirements. Ensure the through-hole footprint matches the target PCB layout. Check for RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component when a 3.9 mH inductance value is required for common mode noise attenuation. The 1 A current handling capability makes it suitable for moderate power applications. Consider the through-hole form factor if surface mount options are not feasible or if mechanical stability is prioritized over board space constraints.
