Procurement Notes
Verify component status as this specific part number may be obsolete or discontinued by the manufacturer. Confirm availability of recommended substitutes such as the MMZ1608R300ATA00 if production continuity is required. Ensure compatibility with existing PCB layouts when considering alternative package sizes. Check official distributor documentation for current manufacturing status and lead times before finalizing procurement plans.
Selection Notes
Select this component for applications requiring 30-ohm impedance at high frequencies with a 1.5A current rating. The 2012 package size offers a balance between performance and board space. Consider the MMZ1608R300ATA00 as a potential smaller footprint substitute if space constraints allow. Verify that the multi-layer construction meets the thermal and mechanical requirements of the target environment.
Part Context
This ferrite bead belongs to the TDK MMZ series, which focuses on noise reduction for general signal lines. The series offers various frequency characteristics using eight different materials. The MMZ2012R300AT000 specifically targets the 2012 metric package size, providing a standard solution for surface-mount applications where moderate current handling and specific impedance values are necessary for signal integrity.
Replacement Considerations
The MMZ1608R300ATA00 is listed as a recommended substitute. Note that this alternative has a smaller 1608 package size compared to the original 2012 package. Verify PCB layout compatibility and ensure the substitute meets all electrical specifications including impedance and current ratings.
