PZ1608U391-1R0TF

Overview

The PZ1608U391-1R0TF is a multilayer chip ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0603 (1608 metric) package and provides an impedance of 390 ohms at 100 MHz with a tolerance of ±25%. The component supports a rated current of 1A and exhibits a maximum DC resistance of 140 milliohms. Designed for single-line applications, it serves as a passive electronic component for noise suppression in high-frequency circuits.

Feature Summary

• Multilayer construction for compact surface-mount integration
• High impedance characteristics for effective electromagnetic interference suppression
• Capable of handling rated currents up to 1A without saturation

Applications

• Noise suppression in digital signal lines
• Power line filtering in consumer electronics
• EMI reduction in communication equipment

Procurement Notes

Verify the manufacturer designation explicitly as Shenzhen Sunlord Electronics Co., Ltd. when sourcing. Confirm the part number suffix matches the standard tape-and-reel configuration. Ensure compliance with RoHS directives if required by the end application. Cross-reference the impedance value of 390 ohms at 100 MHz against circuit requirements to validate performance suitability.

Selection Notes

Select this component for designs requiring a 0603 footprint with specific attenuation needs at 100 MHz. The 1A current rating makes it suitable for power rails or data lines carrying moderate loads. Consider the 140 milliohm DC resistance impact on voltage drop in low-voltage systems. Evaluate thermal dissipation capabilities relative to the ambient operating environment and PCB copper area.

Part Context

This component belongs to the PZ series of multilayer chip ferrite beads from Sunlord. The series is engineered for general-purpose noise suppression in portable devices and industrial electronics. The 0603 size offers a balance between current handling capacity and board space efficiency compared to smaller packages like 0402.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers based on identical impedance curves, current ratings, and physical dimensions before implementation.
