HZ0402B102R-10

Chip Ferrite Bead Overview

HZ0402B102R-10 is a high-frequency differential mode ferrite chip bead from the HZ series, manufactured by Laird-Signal Integrity Products. It features a 0402 (1005 metric) surface-mount package with SMD/SMT termination. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 200 mA. Its maximum DC resistance is specified as 1 Ohm. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through differential mode filtering capabilities.
• Utilizes a compact monolithic construction suitable for space-constrained surface-mount applications.

Chip Ferrite Bead Applications

• High-speed signal line filtering
• Power line noise attenuation in portable electronics

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as some listings reference Qnity while others cite Laird-Signal Integrity Products. Confirm that the 200 mA current rating aligns with your circuit requirements, noting discrepancies with other models in the same series that may support higher currents. Ensure the 1 Ohm DC resistance specification matches your power loss constraints before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 1 kOhms impedance at 100 MHz is required for EMI suppression in tight spaces. The 0402 footprint allows for dense PCB layouts. Consider the 200 mA current limit carefully; if higher current handling is needed, larger packages such as 0805 or 1206 from the same series should be evaluated instead.

Chip Ferrite Bead Part Context

This part belongs to the HZ series of ferrite beads designed for high-frequency applications. It complements other Laird components like the HZ0805D102R-10 and HZ1206D102R-10, which offer similar impedance characteristics but in larger packages to handle higher current loads. The series focuses on providing effective noise filtering across various form factors.

Chip Ferrite Bead Replacement Considerations

HZ0402C601R-10 offers lower impedance (600 Ohms). HZ0402A152R-10 provides higher impedance (1.5 kOhms) but significantly lower current capacity (50 mA). For higher current needs, consider HZ0805D102R-10 or HZ1206D102R-10.
