UPZ1608U280-4R0TF

Overview

The UPZ1608U280-4R0TF is a single-channel power line ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. in a 0603 (1608 Metric) surface-mount package. It exhibits an impedance of 28 Ohms at 100 MHz with a tolerance of ±25%. The component supports a rated current of 4 Amperes and features a low DC resistance of 4 milliohms, designed for efficient noise suppression in high-current applications.

Feature Summary

• Utilizes a multilayer stacked structure with internal silver electrodes to minimize signal crosstalk and ensure shielding integrity.
• Provides superior EMI suppression across a broad frequency range while maintaining lower DC resistance compared to traditional large-current beads.
• Offers enhanced reliability through a monolithic ceramic construction capable of withstanding high current loads.

Applications

• Noise suppression on power lines in communication equipment
• EMI filtering for audio and video devices
• Power line noise reduction in computer peripherals

Procurement Notes

Verify the manufacturer part number against official Sunlord documentation to confirm specifications. Ensure the component matches the required 0603 footprint and 4A current rating for your specific circuit design. Cross-reference datasheets for impedance and DC resistance values before integration.

Selection Notes

Select this component when space constraints require a 0603 package but high current handling is necessary. The low DC resistance minimizes voltage drop and power loss in power delivery networks. Evaluate the 28 Ohm impedance profile to ensure it aligns with the target noise frequencies in the application.

Part Context

This ferrite bead belongs to the UPZ series from Sunlord, which focuses on high-current power line applications. The series is characterized by its multilayer technology, offering compact solutions for EMI suppression in portable and industrial electronics where space and current capacity are critical factors.
