- High current handling capability
- Compact 0402 surface-mount footprint
Applications
- Automotive body and chassis circuits
- Automotive infotainment systems
- Industrial equipment filtering
Procurement Notes
Verify the specific suffix against manufacturer documentation, as variations may exist between TV and T designations. Confirm current availability status, as this component type may be subject to discontinuation or limited supply conditions. Ensure compatibility with existing PCB land patterns and reflow soldering profiles specified in the official datasheet.
Selection Notes
Select this component when a compact ferrite bead is required for noise suppression in high-current signal lines. The 68-ohm impedance value targets specific frequency ranges around 100 MHz. Consider the low DC resistance to minimize voltage drop and power loss in power-sensitive automotive or industrial circuits requiring robust EMI filtering.
Part Context
This part belongs to the BK series of multilayer chip beads from Taiyo Yuden, specifically engineered for automotive and industrial use. The HS variant denotes high-current performance within the 0402 package size. It serves as a passive component for electromagnetic interference suppression in dense electronic assemblies where space constraints are critical.
Replacement Considerations
Direct substitutes include Murata BLM15AG601SH1D and Pulse Electronics ABSY00100505601Y00. Verify that alternative components match the 68-ohm impedance, 700 mA current rating, and AEC-Q200 qualification requirements before integration.
