Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to procurement. Confirm that the 0805 package dimensions and terminal configurations match the target PCB layout requirements. Ensure compliance with RoHS3 regulations and check moisture sensitivity level classifications for storage and handling procedures.
Selection Notes
Select this component when a 3A current rating and 220 Ohm impedance at 100 MHz are required for power line filtering. The 0805 package offers a balance between current handling capability and board space efficiency. Consider the low DC resistance to minimize voltage drop and power loss in high-current applications compared to higher resistance alternatives.
Part Context
This part belongs to the ACMS series of multilayer ferrite chip beads manufactured by Max Echo Technologies. The series utilizes ceramic ferrite materials to provide stable impedance characteristics over a wide frequency range. These components are engineered for use in consumer electronics and industrial equipment where space constraints and high current performance are critical design factors.
Replacement Considerations
The CBM05YTAG221 is identified as an equivalent alternative component. Verify that the substitute matches the 220 Ohm impedance, 3A current rating, and 0805 package dimensions before implementation.
