LI0603G221R-10

Chip Ferrite Bead Overview

The LI0603G221R-10 is a monolithic ferrite chip bead manufactured by Laird-Signal Integrity Products. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 1 A and has a maximum DC resistance of 300 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference filtering for power and signal lines
• Utilizes a compact monolithic 0603 surface-mount design
• Maintains stable performance across a wide industrial temperature range

Chip Ferrite Bead Applications

• Power line noise suppression
• Signal line EMI filtering
• High-frequency circuit protection

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation as Laird-Signal Integrity Products or Laird Technologies when sourcing. Confirm the specific impedance value of 220 Ohms at 100 MHz and the 1A current rating against official datasheets. Ensure the 0603 package footprint matches the target PCB layout requirements before finalizing procurement decisions.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring moderate impedance in a small form factor. The 1A current rating suits low-to-medium power circuits. Compare the 300 mOhm DCR against other options if voltage drop is critical. Verify thermal stability needs against the -40°C to +125°C operating range specification.

Chip Ferrite Bead Part Context

This part belongs to the LI series of ferrite beads from Laird-Signal Integrity Products. It is designed for general-purpose EMI suppression in compact electronic assemblies. The 0603 size allows for high-density board layouts while providing effective noise attenuation in both power and signal paths.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes with identical 220 Ohm impedance at 100 MHz and compatible 0603 footprints. Verify that alternative components meet the same 1A current rating and 300 mOhm maximum DC resistance specifications to ensure circuit compatibility.
