Chip Ferrite Bead Procurement Notes

This component is officially classified as Not Recommended for New Designs (NRND) and has been discontinued by TDK Corporation. Verification of end-of-life status is critical before integration. Engineers must confirm availability through authorized distributors or evaluate the manufacturer-recommended substitute MMZ1608S400ATD25 to ensure long-term supply chain stability and compliance with project timelines.

Chip Ferrite Bead Selection Notes

Selection requires consideration of the 500mA current rating and 31 Ohm impedance at 100 MHz for specific signal integrity needs. The 1206 package size dictates board layout constraints. Due to the NRND status, alternative components such as the MMZ1608S400ATD25 should be evaluated for functional equivalence and supply continuity in new production cycles.

Chip Ferrite Bead Part Context

Part of the HF-ACB series, this ferrite bead targets automotive electronics requiring robust noise suppression. It complements TDK's broader magnetic component portfolio by offering AEC-Q200 qualified solutions for harsh environments. The series emphasizes reliability and compact form factors suitable for modern automotive PCB architectures.

Chip Ferrite Bead Replacement Considerations

TDK recommends the MMZ1608S400ATD25 as a direct substitute. This alternative maintains similar automotive-grade specifications and package compatibility, facilitating design migration without significant layout changes.
