HI1206P121R-10

Chip Ferrite Bead Overview

The HI1206P121R-10 is a monolithic ferrite chip bead from the Laird HI series, designed for surface-mount assembly in the 1206 (3216 metric) package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 4 A with a maximum DC resistance of 30 mOhms. It operates within a temperature range of -40°C to +125°C and measures 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height.

Chip Ferrite Bead Feature Summary

• Monolithic construction for high-current power line filtering
• Surface-mount design compatible with standard SMD/SMT processes
• High saturation current capability for power integrity applications

Chip Ferrite Bead Applications

• Power supply output filtering
• DC/DC converter noise suppression
• Signal line EMI mitigation

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation on official documentation, as some listings may display conflicting brand names such as Qnity or Laird. Confirm the specific suffix indicates the correct packaging format. Ensure the part number matches the exact impedance and current ratings required for the target circuit design before procurement.

Chip Ferrite Bead Selection Notes

Select this component when high current handling is required alongside moderate impedance values. The 4 A rating distinguishes it from lower-current variants in the same package size. Verify that the 30 mOhm DCR meets the voltage drop constraints of the application. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Chip Ferrite Bead Part Context

This part belongs to the HI series of high-current ferrite beads manufactured by Laird-Signal Integrity Products. The series is engineered for power integrity solutions where significant DC bias currents must be managed without significant loss of filtering performance. The 1206 footprint offers a balance between current capacity and board space efficiency.

Chip Ferrite Bead Replacement Considerations

Direct replacements within the same family include parts with identical electrical specifications but different packaging suffixes. Cross-manufacturer equivalents require matching the 120 Ohm impedance at 100 MHz, 4 A current rating, and 1206 package dimensions.
