GZ1005U121TF

Chip Ferrite Bead Overview

The GZ1005U121TF is a multilayer chip ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and 0.50mm height. The component provides an impedance of 120 Ohms at 100 MHz and supports a rated current of 1A. Its maximum DC resistance is specified as 120 milliohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Chip Ferrite Bead Feature Summary

• Utilizes multilayer ceramic technology for compact signal line filtering
• Provides high current handling capability suitable for power supply applications
• Offers low DC resistance to minimize insertion loss in circuit paths

Chip Ferrite Bead Applications

• Consumer electronics power filtering
• Signal line noise suppression
• General-purpose EMI suppression in compact devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'U' against the official Sunlord datasheet to confirm the exact current rating and DC resistance parameters, as variations exist within the GZ series. Ensure the ordering code matches the required 1A rating and 120mΩ DCR specifications. Confirm RoHS compliance status and packaging format directly with the manufacturer or authorized distributors prior to purchase.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required with a 1A current capacity. Compare the 120mΩ DC resistance against other variants like the GZ1005D121TF (0.40Ω) to ensure minimal voltage drop. Verify that the 120Ω impedance at 100 MHz aligns with the target noise frequency spectrum for the specific application circuit.

Chip Ferrite Bead Part Context

This part belongs to the Sunlord GZ series of multilayer chip ferrite beads. The series is designed for EMI suppression in portable and consumer electronic devices. The GZ1005U121TF specifically targets applications requiring higher current tolerance than standard low-current variants while maintaining a small form factor.

Chip Ferrite Bead Replacement Considerations

GZ1005D121TF and GZ1005E121TF are listed as parameter equivalents. Note that these substitutes have different current ratings (200mA-500mA) and higher DC resistance values compared to the 1A/120mΩ specification of the U variant.
