GZ1005U421TF

Chip Ferrite Bead Overview

The GZ1005U421TF is a single-line 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 and 0.50mm width. The component provides an impedance of 420 Ohms at 100 MHz and supports a maximum rated current of 100 mA. Its maximum DC resistance is specified as 800 milliohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Multilayer ceramic construction for high-frequency noise suppression
• Compact 0402 surface-mount footprint for space-constrained designs
• Single-line configuration for signal path filtering

Chip Ferrite Bead Applications

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

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'U' against the official Sunlord datasheet to confirm current rating and impedance tolerance, as suffixes often denote distinct electrical characteristics within the GZ series. Ensure the supplier provides traceable documentation confirming compliance with RoHS3 regulations and the stated operating temperature range. Cross-reference the manufacturer part number directly with Sunlord Electronics to avoid substitution errors.

Chip Ferrite Bead Selection Notes

Select this component when a higher impedance value than standard 120 Ohm beads is required for specific frequency attenuation. The 100 mA current rating limits suitability for high-power applications; verify that the circuit's steady-state current remains below this threshold to prevent saturation or excessive heating. The 0402 package requires appropriate PCB land pattern design for reliable soldering.
