NFZ32BW420HN10L

Overview

The NFZ32BW420HN10L is a surface-mount ferrite bead from the Murata EMIFIL NFZ series, designed for EMI suppression in noise ranges from 30 MHz to 1 GHz. 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 42 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 850 mA and has a maximum DC resistance of 288 mOhms. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Designed for radiation noise suppression in the 30 MHz to 1 GHz frequency range
• Compact 1210 surface-mount footprint suitable for space-constrained PCB layouts
• Low DC resistance minimizes power loss in high-current signal paths

Applications

• EMI filtering on high-speed digital data lines
• Noise suppression in portable electronic devices
• Signal integrity protection in consumer electronics

Procurement Notes

Verify the specific suffix HN10L against official Murata documentation to confirm impedance and current ratings. Ensure compatibility with standard 1210 footprints during layout. Check RoHS compliance status via the manufacturer datasheet before integration. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component when a 42 Ohm impedance at 1 MHz is required for broadband noise attenuation. The 850 mA rating suits moderate current applications where low insertion loss is critical. Consider the 1210 package size for balancing performance with board space. Validate thermal performance within the -40°C to +125°C operating range for the target environment.
