NFZ03SG331SN10D

Overview

The NFZ03SG331SN10D is a single-line ferrite bead from the Murata EMIFIL NFZ series, designed for surface-mount applications in the compact 0201 (0603 metric) package. It provides an impedance of 330 Ohms at 900 MHz with a maximum DC resistance of 600 mOhms and a rated current capacity of 305 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.
• Supports automated assembly processes via standard surface-mount packaging options.

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 selected package size and termination style match the target PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when space constraints require a 0201 footprint while maintaining effective noise filtration. Ensure the operating current remains below the 305 mA rating to prevent saturation. Consider the specific impedance curve at 900 MHz to verify compatibility with the targeted interference frequency spectrum.

Part Context

This component belongs to the Murata NFZ series of chip ferrite beads, specifically engineered for electromagnetic interference suppression. The NFZ03SG variant utilizes a shielded design to contain magnetic fields, making it suitable for dense layouts where crosstalk between adjacent components must be minimized.

Replacement Considerations

Consult the official Murata NFZ Part Number Guide for verified substitutes. Cross-reference impedance values and physical dimensions to ensure mechanical and electrical compatibility without redesigning the circuit board.
