LI0603G221R-00

Chip Ferrite Bead Overview

The LI0603G221R-00 is a monolithic ferrite chip bead designed for surface mount applications in the 0603 (1608 metric) package. It provides an impedance of 220 Ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 700 mA. The component features a maximum DC resistance of 300 mOhms and operates within a temperature range of -40°C to +125°C. Physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.95 mm in height. This single-line filter is intended for power and signal line noise suppression.

Chip Ferrite Bead Feature Summary

• Monolithic construction for reliable surface mount integration
• Designed for differential mode noise suppression on power and signal lines
• Compact 0603 footprint suitable for high-density PCB layouts

Chip Ferrite Bead Applications

• Power supply input filtering
• Signal line noise suppression
• General EMI/RFI mitigation in compact electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix '00' against official Laird documentation, as it may indicate an obsolete or discontinued status compared to the active '10' variant. Confirm RoHS compliance and REACH status directly from the manufacturer's datasheet before procurement. Ensure the 700 mA current rating meets the application requirements to prevent saturation.

Chip Ferrite Bead Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for a single-line circuit with a 700 mA current capacity. The 0603 package size is appropriate for space-constrained designs. Compare the 300 mOhm DCR against voltage drop requirements. Consider the LI0603G221R-10 if the '00' suffix denotes an obsolete version.

Chip Ferrite Bead Part Context

This part belongs to the Laird Signal Integrity Products ferrite bead family, specifically the LI series. These components are engineered for electromagnetic interference suppression in electronic circuits. The brand specializes in signal integrity solutions, providing materials and components that protect devices from harmful noise and heat.

Chip Ferrite Bead Replacement Considerations

Public sources identify LI0603G221R-00 as obsolete. The LI0603G221R-10 is a verified substitute with identical electrical parameters (220 Ohms @ 100 MHz, 700 mA, 300 mOhm DCR) but a slightly lower profile height of 0.8 mm. Verify pin compatibility and thermal characteristics during substitution.
