NFZ03SG671SN10D

Overview

The NFZ03SG671SN10D is a single-line ferrite bead from Murata Electronics, designed for surface-mount assembly in the compact 0201 (0603 metric) package. It provides an impedance of 670 Ohms at 900 MHz with a maximum DC resistance of 850 milliohms and a rated current of 250 mA. The component operates within a temperature range of -55°C to +125°C and measures 0.60 mm in length, 0.30 mm in width, and 0.33 mm in height.

Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 900 MHz.
• Features a low DC resistance profile to minimize signal loss and power dissipation in sensitive circuits.
• Utilizes a shielded construction to contain electromagnetic interference effectively.
• Supports automated surface-mount manufacturing processes due to its standardized chip form factor.

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation
• RF circuit interference suppression

Procurement Notes

Verify the complete part number against official Murata documentation to ensure correct impedance and tolerance specifications. Confirm that the 0201 package dimensions align with the target PCB footprint. Check RoHS compliance status if required by specific environmental regulations. Ensure handling procedures account for the small physical size during assembly.

Selection Notes

Select this component when space constraints require a 0201 footprint and the application demands 670 Ohms of impedance at 900 MHz. Evaluate the 250 mA current rating against the maximum expected load current to prevent saturation. Consider the 850 milliohm DC resistance impact on voltage drop. Compare thermal performance within the specified -55°C to +125°C operating range.

Part Context

This component belongs to the Murata NFZ series of EMIFIL ferrite beads. The series offers various impedance values and current ratings across multiple standard package sizes. The NFZ03SG variant specifically denotes the 0201 case size with shielded construction, providing consistent performance for compact electronic designs requiring reliable EMI mitigation.

Replacement Considerations

Consult the official Murata NFZ Part Number Guide for verified substitutes. Cross-reference impedance values at 900 MHz and maximum current ratings. Ensure replacement parts match the 0201 package dimensions and mounting requirements. Verify compatibility with existing PCB footprints and assembly processes.
