LI1206H121R-10

Chip Ferrite Bead Overview

The LI1206H121R-10 is a monolithic ferrite chip bead from the Laird LI series, designed for power and signal line filtering. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.6 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 150 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Monolithic construction for reliable high-frequency noise suppression in compact designs
• Single-line configuration optimized for individual power and signal path filtering
• Surface-mount termination compatible with standard SMD/SMT assembly processes

Chip Ferrite Bead Applications

• Power supply input filtering
• Signal line EMI suppression
• High-speed digital circuit noise reduction

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Laird-Signal Integrity Products documentation to ensure authenticity. Confirm that the specific suffix matches the required impedance and current ratings. Check RoHS compliance status as specified in the latest datasheet. Ensure the package type corresponds to the 1206 footprint requirements of your PCB design before procurement.

Chip Ferrite Bead Selection Notes

Select this component when a single-line ferrite bead with 120 Ohm impedance at 100 MHz is required. Ensure the application current does not exceed 800 mA to prevent saturation. Verify that the 1206 package size fits the available board space. Consider the 150 mOhm DC resistance impact on voltage drop if used in low-voltage power rails.

Chip Ferrite Bead Part Context

This component belongs to the Laird LI series of ferrite chip beads. It serves as a direct replacement for the discontinued LI1206H121R-00 model. The LI series is engineered for general-purpose electromagnetic interference filtering in consumer electronics and industrial applications requiring compact passive components.

Chip Ferrite Bead Replacement Considerations

LI1206H121R-10 is the direct replacement for the obsolete LI1206H121R-00.
