NFZ32BW9R8HN11L

Overview

The NFZ32BW9R8HN11L is a single-line ferrite bead from the Murata EMIFIL NFZ series, designed for EMI suppression in surface-mount applications. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height. The component provides an impedance of 9.8 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 2.1 A and has a maximum DC resistance of 53 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies.
• Designed for surface-mount technology integration on printed circuit boards.
• Capable of handling continuous direct current loads up to 2.1 amperes.

Applications

• General-purpose EMI filtering in electronic circuits
• Noise suppression on signal lines
• Power line filtering for low-noise requirements

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check official datasheets for impedance curves and thermal derating information before finalizing design integration.

Selection Notes

Select this component when a 9.8 Ohm impedance at 1 MHz is required for noise attenuation. Ensure the 2.1 A current rating meets the circuit's operational demands. Consider the 1210 footprint constraints and verify that the 53 mOhm DC resistance does not cause excessive voltage drop in the application.

Part Context

This component belongs to the Murata NFZ series of ferrite beads, specifically the NFZ32BW sub-series. These components are engineered for radiation noise suppression in the 30 to 150 MHz range. The NFZ32BW9R8HN11L utilizes a standard 1210 case size, making it suitable for compact consumer electronics and industrial equipment designs requiring reliable EMI control.

Replacement Considerations

Direct substitutes include other Murata parts from the NFZ32BW series with matching impedance and current ratings, such as NFZ32BW9R8HN11K. Cross-manufacturer replacements require verifying identical impedance profiles, current handling capabilities, and physical footprint compatibility.
