HZ0805D102R-00

Chip Ferrite Bead Overview

The HZ0805D102R-00 is a monolithic ferrite bead from the Laird HZ series, designed for EMI filtering in power and signal lines. It features a 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm x 1.10mm. The component provides an impedance of 1 kOhms at 100 MHz and supports a maximum DC current of 400mA. Its maximum DC resistance is specified as 300mOhms to 400mOhms depending on the source variant. It operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in single-line configurations.
• Monolithic construction ensures reliability in surface-mount assembly processes.
• Rated for operation across extended industrial temperature ranges.

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Signal line noise suppression in consumer electronics
• EMI mitigation in compact circuit boards requiring 0805 footprints

Chip Ferrite Bead Procurement Notes

Verify RoHS compliance status carefully, as some sources indicate non-compliance while others list detailed specifications. Confirm the exact DCR value (300mOhm vs 400mOhm) required for your design, as variants exist. Check for active replacement part numbers like HZ0805D102R-10 if supply continuity is critical. Ensure the specific datasheet version matches the manufacturing date code.

Chip Ferrite Bead Selection Notes

Select this component when a 1kOhm impedance at 100MHz is required for a single-line application. The 400mA current rating suits low-power signal or auxiliary power rails. The 0805 package allows for dense PCB layouts. Compare against the MI series if higher current handling is needed, or the LI series for different impedance characteristics.

Chip Ferrite Bead Part Context

This part belongs to the Laird HZ series of ferrite beads, which are optimized for high-frequency noise suppression. The HZ series typically offers high impedance values in small packages. The suffix '-00' often denotes specific packaging or compliance variations compared to '-10' variants. It is distinct from the MI and LI series which may have different current ratings or impedance profiles.

Chip Ferrite Bead Replacement Considerations

HZ0805D102R-10 is listed as a direct substitute. Verify that the replacement matches the exact DCR and impedance tolerances required by the original design specification.
