HZ0805B222R-10

Chip Ferrite Bead Overview

The HZ0805B222R-10 is a single-line ferrite chip bead from the Laird HZ series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 2.2 kOhms at a test frequency of 100 MHz. The component supports a maximum DC current of 200 mA and exhibits a maximum DC resistance of 700 mOhms. It operates within a temperature range of -40°C to +125°C. Physical dimensions are 2 mm length, 1.25 mm width, and 1.25 mm height.

Chip Ferrite Bead Feature Summary

• Designed for high-frequency noise suppression on power and signal lines
• Compact surface-mount form factor suitable for space-constrained PCB layouts
• Capable of handling moderate DC bias currents with low insertion loss

Chip Ferrite Bead Applications

• High-frequency EMI/RFI filtering on digital signal lines
• Noise attenuation on compact power supply rails
• Signal integrity enhancement in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation carefully, as some listings may display conflicting vendor names such as Qnity or generic identifiers instead of Laird-Signal Integrity Products. Confirm the specific impedance value of 2.2 kOhms and the 0805 package size against official datasheets to ensure compatibility with design requirements. Check RoHS compliance status directly from the manufacturer's documentation.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required for noise suppression in small footprints. Ensure the circuit current does not exceed the 200 mA rating to prevent saturation. Compare the 700 mOhm DC resistance against voltage drop constraints. Verify that the 0805 package fits the available board space and thermal management strategy.

Chip Ferrite Bead Part Context

This part belongs to the Laird HZ series of ferrite beads, which are engineered for signal integrity applications. The series offers various impedance values in standard SMD packages. The HZ0805B222R-10 specifically targets high-impedance filtering needs in the 0805 footprint, distinguishing it from lower-impedance variants in the same family.
