NFZ2HBM2R9SZ10L

Overview

The NFZ2HBM2R9SZ10L is a single-channel chip noise filter from the Murata EMIFIL NFZ series, designed for surface-mount assembly. It features an impedance of 2.9 Ohms at a test frequency of 1 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.1 A and exhibits a maximum DC resistance of 85 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 2.5 mm in length, 2 mm in width, and 0.9 mm in height, housed in a compact SMD package suitable for space-constrained PCB layouts.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency noise attenuation
• Utilizes a compact surface-mount footprint for efficient board space utilization
• Engineered for stable performance across extended industrial temperature ranges

Applications

• General electronic equipment EMI filtering
• Consumer device signal line protection
• Industrial control circuit noise suppression

Procurement Notes

Verify the specific suffix 'SZ' against official Murata documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with standard reflow soldering profiles for SMD components. Cross-reference the impedance value at 1 MHz with design requirements. Confirm RoHS compliance status via the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when low impedance is required for power or data lines carrying up to 1.1 A. The 2.9 Ohm rating targets specific high-frequency noise bands. Consider the 0806 metric size for routing density. Evaluate thermal dissipation capabilities given the 85 mOhms DC resistance under load conditions to ensure reliability in the target application environment.

Part Context

This ferrite bead belongs to the NFZ family of EMI filters manufactured by Murata Electronics. The series offers various impedance and current ratings tailored for different EMC needs. The NFZ2HBM2R9SZ10L specifically addresses applications requiring moderate current handling with precise low-impedance characteristics in a small form factor.

Replacement Considerations

Check for direct substitutes within the NFZ series having identical 2.9 Ohm impedance and 1.1 A current rating. Verify that alternative parts match the 2.5x2x0.9 mm package dimensions and operating temperature range. Ensure equivalent DC resistance values to maintain circuit performance integrity.
