Common Mode Chokes Feature Summary

Magnetically compensated construction minimizes stray magnetic fields
Flat profile facilitates compact PCB integration
Designed for single-phase common mode noise suppression

Common Mode Chokes Applications

Single-phase power line filtering
Common mode interference suppression in electronic equipment
PCB-mounted EMI mitigation circuits

Common Mode Chokes Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 27 mH inductance and 1.4 A current ratings align with the target circuit requirements. Ensure the through-hole footprint matches the PCB layout specifications to guarantee proper mechanical fit and electrical performance.

Common Mode Chokes Selection Notes

Select this component when a low-profile, magnetically compensated solution is required for single-phase lines. The 27 mH inductance offers significant attenuation for common mode noise. The 1.4 A current handling capacity suits moderate power applications. Verify thermal performance within the intended operating environment.
