UPZ1005D121-1R3TF

Overview

The UPZ1005D121-1R3TF is a multilayer chip ferrite bead from the UPZ series, manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0402 (1005 Metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. The component provides an impedance of 120 Ohms at 100 MHz for single-signal line applications. It supports a maximum current rating of 1.3A and has a maximum DC resistance (DCR) of 90 milliohms. The device operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Utilizes internal silver electrode multilayer structure for reliable performance
• Offers ferrite shielding to prevent crosstalk between signal lines
• Provides lower DC resistance compared to traditional large-current ferrite beads
• Features monolithic construction for enhanced mechanical reliability

Applications

• High-speed digital signal line filtering
• Power supply noise suppression in compact circuits
• EMI reduction in portable electronic devices
• Signal integrity enhancement in high-density PCB layouts

Procurement Notes

Verify the complete part number including the suffix to ensure correct current and resistance specifications. Confirm package compatibility with automated placement equipment. Check manufacturing date codes for moisture sensitivity handling if required. Ensure storage conditions align with manufacturer guidelines to maintain component integrity before soldering.

Selection Notes

Select this component when low DC resistance is critical for high-current applications requiring 1.3A capacity. The 0402 footprint suits space-constrained designs needing 120 Ohm attenuation at 100 MHz. Compare DCR values against alternative series like GZ or PZ if different current ratings are needed. Ensure thermal management capabilities match the operating environment requirements.

Part Context

This part belongs to the UPZ series of multilayer chip ferrite beads designed for high-current applications. It differs from standard signal-line ferrites by offering significantly higher current tolerance while maintaining small form factors. The series targets modern electronics where space efficiency and power handling must coexist without compromising signal quality.

Replacement Considerations

Direct substitutes include other UPZ series parts with identical electrical characteristics. Cross-reference with GZ1005D121CTF if lower current ratings are acceptable. Verify pinout and physical dimensions match existing board footprints before substitution.
