NFZ32BW320HZ10L

Overview

The NFZ32BW320HZ10L is a ferrite bead from the Murata EMIFIL NFZ series, designed for EMI suppression in electronic circuits. It features a 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height. The component provides an impedance of 32 Ohms at the test frequency of 100 MHz. It supports a maximum DC current of 1 A and has a maximum DC resistance of 160 mOhms. The unit operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides effective electromagnetic interference (EMI) filtering through high-impedance characteristics at target frequencies.
• AEC-Q200 qualified for automotive reliability standards.
• Compact 1210 surface-mount footprint suitable for space-constrained PCB layouts.

Applications

• Automotive electronics systems requiring AEC-Q200 compliant components
• Power supply lines for noise suppression
• Signal line filtering in digital circuits

Procurement Notes

Verify the specific suffix HZ10L against official Murata documentation to confirm impedance tolerance and packaging details. Ensure the procurement channel sources genuine parts with valid traceability. Cross-reference the datasheet revision date to ensure compatibility with current design specifications. Confirm RoHS compliance status as indicated in the manufacturer's latest release notes before finalizing orders.

Selection Notes

Select this component when a 32 Ohm impedance at 100 MHz is required for EMI suppression. The 1 A current rating must align with the circuit's operational load to prevent saturation. The 1210 package size should be evaluated against available PCB real estate. Consider the 160 mOhms DC resistance impact on voltage drop if used in low-voltage power paths. Verify thermal performance within the -40°C to +125°C operating range.

Part Context

This part belongs to the Murata NFZ series of chip noise filters. These components are engineered for high-performance EMI suppression in compact form factors. The series is widely utilized in consumer, industrial, and automotive applications where reliable noise reduction is critical for signal integrity and regulatory compliance.

Replacement Considerations

Direct substitutes must match the 1210 package, 32 Ohm impedance at 100 MHz, and 1 A current rating. Verify equivalent DC resistance and temperature coefficients. Check for compatible AEC-Q200 qualification if automotive use is intended. Consult Murata's official replacement guide for validated alternatives.
