Common Mode Chokes Procurement Notes

This component is officially obsolete and no longer manufactured by Tamura. Procurement should focus on verified surplus stock or authorized distributors holding remaining inventory. Buyers must confirm part authenticity and storage conditions due to the end-of-life status. Cross-referencing with approved substitutes is recommended for new designs.

Common Mode Chokes Selection Notes

Designers requiring this specification should evaluate the ALFT-03A-8 as a functional alternative. The substitute offers similar inductance but differs in current handling and physical dimensions. Verify pin compatibility and thermal performance before integration. The CMF-0056 remains suitable only for maintenance or repair scenarios where original specifications are mandatory.

Common Mode Chokes Part Context

The CMF-0056 belongs to Tamura’s CMF series of common mode chokes, designed for electromagnetic interference reduction. This specific model targets applications requiring moderate inductance with compact vertical packaging. Its discontinuation reflects product lifecycle management, prompting migration to newer series components that offer improved availability and updated manufacturing processes.
