HI2220R181R-00

Chip Ferrite Bead Overview

The HI2220R181R-00 is a single-line surface-mount ferrite bead from the HI series, manufactured by Laird-Signal Integrity Products. Designed for power and signal line filtering, it features a 2220 (5650 Metric) package with dimensions of 0.220 inches long by 0.200 inches wide. The component provides an impedance of 180 Ohms at 100 MHz and supports a maximum rated current of 5A. It has a maximum DC resistance of 20 milliohms and operates within a temperature range of -40°C to 125°C. This part is currently obsolete.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for power and signal lines
• Supports high-current applications up to 5A
• Designed for surface-mount installation in compact footprints

Chip Ferrite Bead Applications

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

Chip Ferrite Bead Procurement Notes

Verify component obsolescence status before procurement planning. Confirm availability of direct replacements such as the HI2220R181R-10 variant. Ensure design updates accommodate RoHS compliance differences if transitioning from non-compliant legacy stock to current production runs.

Chip Ferrite Bead Selection Notes

Select this component for designs requiring 180 Ohm impedance at 100 MHz in a 2220 package. Verify that the 5A current rating meets circuit requirements. Check thermal management needs given the 20 milliohm DC resistance. Consider the obsolete status when defining long-term supply chain strategies.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HI series of high-current components. It shares the 2220 footprint with other variants like the HI2220P171R-00 and HI2220R151R-00. These components are engineered for dense PCB layouts where space constraints require larger packages to handle significant current loads while maintaining effective noise filtration.

Chip Ferrite Bead Replacement Considerations

The HI2220R181R-10 is a direct replacement. Verify RoHS3 compliance and packaging format changes.
