Chip Ferrite Bead Procurement Notes

Verify the obsolete status of this specific part number before procurement planning, as availability may be limited or discontinued by the manufacturer. Confirm that any substitute components meet the exact electrical specifications, particularly impedance and current ratings, to ensure circuit compatibility. Check for updated datasheets regarding material changes or end-of-life notifications from Taiyo Yuden.

Chip Ferrite Bead Selection Notes

Select this component when a 390 Ohm impedance at 100 MHz is required for single-line power filtering in a 0603 package. Ensure the application current does not exceed 1.0 A to prevent saturation. Consider thermal derating if operating near the upper temperature limit of 100°C. Verify that the low DC resistance of 100 milliohms aligns with voltage drop constraints in the power path.

Chip Ferrite Bead Part Context

This component belongs to the BK series of multilayer chip bead inductors from Taiyo Yuden, specifically engineered for automotive and industrial power line applications. The HS designation typically indicates high-surge current capability within the series. These devices utilize ceramic ferrite materials to provide effective broadband noise attenuation while maintaining structural integrity under mechanical stress.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include MH1608-101Y from Bourns Inc., which offers similar form factor and function. Verify impedance and current ratings match requirements when selecting alternatives.
