HZ0402C102R-10

Chip Ferrite Bead Overview

The HZ0402C102R-10 is a differential mode ferrite chip bead from the Laird HZ series, designed for high-frequency noise suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.01 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz and has a maximum DC resistance of 1 Ohm. It supports a maximum DC current of 300 mA and operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides broadband differential mode noise attenuation for high-frequency signal lines
• Utilizes a compact 0402 surface-mount footprint for dense PCB layouts
• Engineered for stable performance across industrial temperature ranges

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply noise suppression in compact electronics
• EMI reduction in mobile communication devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and manufacturer designation upon ordering, as sourcing data indicates potential discrepancies between Laird-Signal Integrity Products and Qnity branding for this part number. Confirm RoHS compliance status directly with the supplier, as available documentation lists varying compliance details. Ensure the requested packaging format matches your assembly requirements, as options include cut tape, reel, or MouseReel formats depending on the distributor.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance of 1 Ohm is required alongside significant high-frequency attenuation. The 300 mA current rating suits moderate power applications where space is constrained. Compare against the HZ0402B102R-10 if higher current handling is needed, or the HZ0402A152R-10 if higher impedance is prioritized over current capacity. Ensure the 0402 package fits the design constraints.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HZ series of passive components manufactured by Laird-Signal Integrity Products. The series focuses on providing reliable EMI suppression solutions in small form factors. The HZ0402C102R-10 specifically addresses the need for differential mode filtering in modern electronic designs where board real estate is limited and signal integrity is critical.

Chip Ferrite Bead Replacement Considerations

HZ0402B102R-10 offers similar impedance but higher current capability. HZ0402A152R-10 provides higher impedance but lower current handling. Verify pin compatibility and thermal characteristics before substitution.
