Procurement Notes
Verify the specific suffix and revision level against the manufacturer's latest datasheet, as legacy parts may have discontinued status or updated specifications. Confirm availability through authorized distributors, noting that this model may be subject to end-of-life restrictions or limited stock conditions depending on the region and supplier.
Selection Notes
Select this component when a low-profile 0402 ferrite bead is required for EMI filtering in space-constrained automotive or industrial designs. Ensure the 450 mA current rating meets the circuit's DC load requirements and that the 120 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Verify thermal performance within the specified -55°C to +125°C operating range.
Part Context
This part belongs to Taiyo Yuden's BK series of multilayer chip bead inductors. These components are engineered specifically for automotive electronics, offering robust performance in harsh environments. The series includes various impedance values and package sizes to support diverse filtering needs across vehicle subsystems.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in the provided documentation. Cross-referencing with similar impedance and package variants from the same manufacturer or other suppliers requires independent verification of electrical parameters and physical dimensions.
