HI0805N221R-10

Chip Ferrite Bead Overview

The HI0805N221R-10 is a single-line differential mode ferrite chip bead manufactured by Laird-Signal Integrity Products. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.00 mm in length, 1.25 mm in width, and a maximum height of 0.90 mm. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 3 A and has a maximum DC resistance of 40 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective electromagnetic interference suppression on power and signal lines
• Designed for compact surface-mount integration in space-constrained circuit layouts
• Capable of handling high continuous DC currents without saturation

Chip Ferrite Bead Applications

• Power supply input filtering
• High-speed signal line noise attenuation
• DC-DC converter output stages

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation as Laird-Signal Integrity Products or Laird Technologies when sourcing. Confirm the RoHS compliance status and specific packaging options such as cut tape or reel availability through authorized distributors. Ensure the part number matches the exact suffix requirements for the desired termination and tolerance specifications.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring robust EMI filtering in a standard 0805 footprint. The 3 A current rating makes it suitable for powering moderate-load circuits. Compare the 220 Ohm impedance profile against other ferrite beads if higher attenuation at different frequencies is required. Consider the low DC resistance to minimize voltage drop and power loss in the signal path.

Chip Ferrite Bead Part Context

This component belongs to the MI/HI series of monolithic ferrite beads from Laird-Signal Integrity Products. These parts are engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The 0805 size offers a balance between current handling capability and board space efficiency compared to smaller packages like 0603.
