PZ0603U121-R45TF

Overview

The PZ0603U121-R45TF is a single-line power line ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0201 (0603 Metric) surface-mount package and belongs to the PZ series. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 450 mA and exhibits a maximum DC resistance of 230 mOhm.

Feature Summary

• Provides high impedance for effective noise suppression in power lines
• Compact 0201 footprint suitable for space-constrained designs
• Single-line configuration for individual circuit protection

Applications

• Portable electronic devices requiring compact filtering
• Power supply input/output noise suppression
• High-frequency signal integrity maintenance in dense PCB layouts

Procurement Notes

Verify the manufacturer designation as Shenzhen Sunlord Electronics Co., Ltd. Confirm the specific impedance value of 120 Ohms at 100 MHz and the 450 mA current rating against official datasheets. Ensure the package size matches the required 0201 (0603 Metric) dimensions for proper board integration.

Selection Notes

Select this component when a low-profile, single-line ferrite bead is needed for power line filtering. The 230 mOhm DC resistance minimizes voltage drop, while the 120 Ohm impedance targets common high-frequency interference. Ensure the operating current does not exceed the 450 mA limit to maintain performance.

Part Context

This part is part of Sunlord's PZ series of ferrite beads, designed for general-purpose noise suppression. It serves as a functional equivalent to other industry-standard components like the TDK MMZ0603S121HT000, offering similar electrical characteristics within the same physical form factor.

Replacement Considerations

The TDK MMZ0603S121HT000 is listed as a parametric equivalent. Verify that the substitute maintains identical impedance, current rating, and package dimensions before implementation.
