UPZ1608E331-1R7TF

Overview

The UPZ1608E331-1R7TF is a single-line power line ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0603 (1608 Metric) surface-mount package designed for high-current applications. The component provides an impedance of 330 Ohms at 100 MHz with a tolerance of ±25%. It supports a rated current of 1.7 Amperes and exhibits a maximum DC resistance of 80 milliohms.

Feature Summary

• Designed specifically for power line noise suppression in electronic circuits
• Capable of handling high direct current loads up to 1.7 Amperes
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• High-speed digital signal line protection

Procurement Notes

Verify the part number against official Sunlord documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical characteristics, particularly the 1.7A rating and 330 Ohm impedance. Request original manufacturer packaging and date codes to guarantee component integrity and traceability during the sourcing process.

Selection Notes

Select this component when circuit design requires effective high-frequency noise attenuation on power rails carrying significant current. The low DC resistance minimizes voltage drop and power loss, while the high current rating prevents saturation. Ensure the 0603 package size aligns with the available PCB real estate and manufacturing capabilities.

Part Context

This ferrite bead belongs to the UPZ series from Sunlord, which focuses on power line applications. The series utilizes multi-layer chip technology to provide reliable electromagnetic interference suppression. The 0603 form factor represents a standard industry size for balancing performance with board space efficiency in modern consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult official Sunlord catalogs or authorized distributors for qualified alternatives that match the 330 Ohm impedance, 1.7A current rating, and 0603 package dimensions.
