Common Mode Chokes Procurement Notes

This component is officially obsolete and no longer manufactured by Panasonic. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity and condition of any available units, as standard supply channels do not support this part number. Cross-referencing with substitute components is recommended for new designs.

Common Mode Chokes Selection Notes

Designers requiring this specification should evaluate alternative common mode chokes from the same manufacturer or other suppliers. Considerations include matching the 300 mA rating and ensuring compatibility with through-hole assembly processes. Since the original part is discontinued, selecting a modern equivalent with verified performance data is essential for long-term project viability.

Common Mode Chokes Part Context
