NFZ32BW9R8HZ11L

Overview

The NFZ32BW9R8HZ11L is a single-line ferrite bead from Murata’s EMIFIL NFZ series, designed for EMI suppression in the 30 to 150 MHz radiation noise range. It features a compact 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm length, 2.5 mm width, and a maximum height of 1.70 mm. The component provides an impedance of 9.8 Ohms at 1 MHz with a tolerance of ±30%. It supports a rated DC current of 305 mA and maintains a maximum DC resistance of 63.6 mOhms. The device operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression specifically targeting the 30 to 150 MHz frequency spectrum.
• Features low DC resistance to minimize power loss while maintaining high current handling capabilities.
• Utilizes a flat lead 2-SMD package design suitable for automated surface-mount assembly processes.

Applications

• Noise filtering for audio line circuits
• EMI suppression in portable electronic devices
• Signal integrity protection in high-frequency data lines

Procurement Notes

Verify the suffix 'HZ' against official Murata documentation to confirm specific material characteristics or tape/reel specifications, as ordering suffixes may denote variations not always explicit in general summaries. Ensure compatibility with standard reflow soldering profiles by consulting the manufacturer's thermal profile guidelines. Confirm that the 305 mA current rating aligns with the target circuit's peak operational requirements to prevent saturation or excessive heating during continuous use.

Selection Notes

Select this component when application constraints require a balance between moderate current capacity and targeted high-frequency noise attenuation. The 1210 footprint offers a compromise between size and thermal performance compared to smaller packages. Consider the 9.8 Ohm impedance value relative to the target noise frequencies; if higher attenuation is needed at lower frequencies, alternative impedance values within the same series should be evaluated using SimSurfing tools.

Part Context

This part belongs to the NFZ32BW series, which is engineered for robust performance in consumer electronics and industrial applications. The series is characterized by its ability to handle significant DC currents while providing stable impedance characteristics across wide temperature ranges. It serves as a critical passive component for meeting regulatory EMC standards in compact form factors.

Replacement Considerations

Direct substitutes include other NFZ32BW variants with similar impedance and current ratings, such as NFZ32BW9R8HN11L, provided the 'HZ' suffix does not indicate a unique material property requiring exact matching. Cross-reference physical dimensions and terminal configurations to ensure mechanical compatibility on existing PCB layouts.
