Chip Ferrite Bead Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Taiyo Yuden. Procurement must focus on verified direct substitutes from active production lines. Verify that replacement components match the original impedance, current rating, and pinout configuration to ensure circuit compatibility without redesign.

Chip Ferrite Bead Selection Notes

Designers should prioritize components with identical 600 Ohm impedance at 100 MHz and compatible 100 mA current ratings. Ensure the replacement maintains the four-line array structure and 1206 package dimensions. Confirm RoHS compliance and moisture sensitivity levels align with assembly process requirements to prevent reliability issues during soldering.

Chip Ferrite Bead Part Context
