Common Mode Chokes Procurement Notes

This specific part number, ELF-22V035B, is officially classified as obsolete and is no longer manufactured by Panasonic. Procurement efforts should focus on identifying verified substitute components or alternative series within the manufacturer's portfolio that meet equivalent electrical specifications. Verify compatibility before integration into new designs.

Common Mode Chokes Selection Notes

Designers requiring this component must account for its discontinued status. Selection criteria should prioritize substitutes with matching current ratings (3.5A) and similar impedance characteristics. Ensure that any replacement maintains the required form factor for through-hole assembly and complies with relevant safety standards applicable to the target application environment.

Common Mode Chokes Part Context

The ELF-22V035B belongs to Panasonic’s range of common mode chokes, which are passive electromagnetic interference filters. These components are typically utilized to attenuate high-frequency noise traveling along differential lines without affecting the desired signal. The product line supports various current ratings and package types to suit diverse electronic system requirements.

Common Mode Chokes Replacement Considerations

Available substitutes include the ELF-22V040B, which offers a higher current rating of 4A. Designers should verify if the increased current capacity and slight parameter variations are acceptable for the existing circuit design.
