Common Mode Chokes Procurement Notes

Verify the obsolete product status before procurement planning. Confirm that through-hole mounting requirements align with the target PCB design. Ensure the 1A current rating and 20mH inductance meet the specific circuit attenuation needs. Check for available substitute components if new production is required.

Common Mode Chokes Selection Notes

Select this component when through-hole assembly is mandatory for power line filters. The 20mH inductance offers significant impedance for common-mode noise reduction. The 1A current capacity suits moderate power entry applications. Verify thermal performance within the -20°C to 120°C operating range for the specific environment.

Common Mode Chokes Part Context

This part belongs to TDK's common mode choke coil series, specifically designed for power line interference suppression. It serves as a passive filter component to protect downstream electronics from electromagnetic interference conducted along power cables.

Common Mode Chokes Replacement Considerations

The product status is listed as Obsolete. Public confirmed substitute part numbers are not provided in the source data. Engineers must identify equivalent through-hole common mode chokes with matching 20mH inductance and 1A current ratings.
