LI0402C221R-10

Chip Ferrite Bead Overview

The LI0402C221R-10 is a single-line ferrite chip bead designed for power and signal line filtering. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.01mm length, 0.50mm width, and 0.65mm height. The component provides an impedance of 220 Ohms at 100 MHz. It supports a maximum DC current rating of 300mA and has a maximum DC resistance of 350mOhm. The operating temperature range spans from -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression for high-frequency noise on power and signal lines
• Compact 0402 surface-mount footprint suitable for space-constrained printed circuit board layouts
• Capable of handling continuous DC currents up to 300mA without saturation

Chip Ferrite Bead Applications

• Power supply input filtering in portable electronic devices
• Signal line noise suppression in data communication interfaces
• EMI mitigation in compact consumer electronics assemblies

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'R-10' against official Laird documentation to confirm reel packaging specifications. Ensure compatibility with standard 0402 reflow soldering profiles. Confirm RoHS3 compliance status through current manufacturer declarations before integration into regulated products.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for 220 Ohm attenuation at 100 MHz. The 300mA current rating suits moderate power applications. Verify that the 350mOhm DC resistance meets system voltage drop requirements. Consider thermal management within the -40°C to +125°C operational envelope.

Chip Ferrite Bead Part Context

This part belongs to the Laird Signal Integrity Products ferrite bead portfolio. It serves as a passive EMI filter component. The LI series indicates a specific material formulation optimized for broadband noise absorption. It complements other Laird filtering solutions for comprehensive signal integrity management.

Chip Ferrite Bead Replacement Considerations

Cross-reference with Laird LI0402C221R variants or equivalent 0402 ferrite beads offering 220 Ohms @ 100 MHz. Verify identical current ratings and physical dimensions for direct replacement. Consult official substitution guides for material property equivalencies.
