HI2220Q401R-00

Chip Ferrite Bead Overview

The HI2220Q401R-00 is a single-line ferrite bead designed for power line filtering applications. It features a surface-mount package with dimensions of 2220 (5650 metric). The component provides an impedance of 400 Ohms at 100 MHz and supports a maximum rated current of 4.5A. Its maximum DC resistance is 25 milliohms, ensuring low insertion loss in high-current circuits. The device operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on power lines through high impedance characteristics at target frequencies.
• Supports high current loads up to 4.5A with minimal voltage drop due to low DC resistance.
• Utilizes a robust surface-mount footprint suitable for automated assembly processes.

Chip Ferrite Bead Applications

• Power supply input filtering
• DC bus line noise suppression
• High-current signal path conditioning

Chip Ferrite Bead Procurement Notes

Verify the specific suffix designation when sourcing replacements, as it may indicate compliance variations or packaging differences. Confirm that the 4.5A current rating aligns with the thermal management requirements of the target application. Ensure the 2220 package dimensions fit the available PCB real estate without compromising clearance rules.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant attenuation of high-frequency noise on power rails carrying currents up to 4.5A. The 400 Ohm impedance at 100 MHz makes it suitable for suppressing switching noise from converters. Consider the 25 milliohm DCR impact on overall efficiency if voltage headroom is critical.

Chip Ferrite Bead Part Context

This part belongs to the HI series of ferrite beads from Laird-Signal Integrity Products, specifically engineered for signal integrity and EMI control. The 2220 package size indicates a larger form factor compared to standard chip resistors, allowing for higher current handling capabilities and thermal dissipation.
