Common Mode Chokes Procurement Notes

This component is officially listed as obsolete and end-of-life by the manufacturer. Procurement must rely exclusively on secondary market distributors or surplus inventory holders. Verify the authenticity and physical condition of available stock, as original manufacturing support and direct ordering from Panasonic are unavailable. Ensure substitute components meet identical electrical specifications for compatibility.

Common Mode Chokes Selection Notes

Engineers should evaluate alternative components due to the obsolete status of this part. Selection criteria must prioritize matching the 10 mH inductance and 1 A current handling capabilities. Consider modern equivalents that offer similar form factors and thermal performance to ensure long-term reliability and availability for future production cycles without supply chain disruptions.

Common Mode Chokes Part Context

The ELF series represents Panasonic's legacy line of common mode chokes designed for general-purpose noise suppression. These components were widely used in various electronic assemblies requiring reliable EMI/RFI mitigation. The ELF-18D431F specifically targets applications needing robust common mode attenuation with standard through-hole integration capabilities.

Common Mode Chokes Replacement Considerations

Available substitutes include the EH24-1.0 series. Verify that replacement parts match the 10 mH inductance and 1 A current ratings. Ensure the substitute supports through-hole mounting and compatible operating temperatures.
