NFZ32BW420HZ10L

Overview

The NFZ32BW420HZ10L is a single-channel chip noise filter from the Murata EMIFIL NFZ series, designed for EMI suppression. It features an impedance of 42 Ohms at a test frequency of 1 MHz with a tolerance of 30%. The component supports a maximum DC current of 1.6 A and has a maximum DC resistance of 75 mOhms. It operates within a temperature range of -40°C to +125°C. The device utilizes SMD/SMT termination and is housed in a 1210 (3225 metric) package measuring 3.2 mm in length, 2.5 mm in width, and 1.55 mm in height.

Feature Summary

• Designed for radiation noise suppression in the 30 to 150 MHz frequency range
• Generates high impedance within a compact surface-mount package
• Complies with AEC-Q200 qualification standards for automotive reliability

Applications

• Automotive electronic circuits requiring EMI filtering
• High-frequency noise suppression in mobile devices
• General-purpose EMI filters in consumer electronics

Procurement Notes

Verify the specific suffix HZ10L against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance and current ratings for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and active status before procurement.

Selection Notes

Select this component when a 42 Ohm impedance is required at 1 MHz for noise attenuation. The 1.6 A current rating suits power lines or signal paths with moderate current loads. The 1210 footprint allows for standard surface-mount assembly processes. Verify that the operating temperature range meets the environmental requirements of the final application.

Part Context

This ferrite bead belongs to the Murata NFZ series, which specializes in components for radiation noise ranges between 30 and 150 MHz. The series emphasizes achieving high impedance values within small physical packages to facilitate dense PCB layouts. As part of the EMIFIL product line, it addresses electromagnetic interference challenges in modern electronic systems.

Replacement Considerations

Direct substitutes must match the 1210 package, 42 Ohm impedance at 1 MHz, and 1.6 A current rating. Verify equivalent thermal characteristics and AEC-Q200 compliance if used in automotive applications. Consult Murata's official cross-reference tools for validated alternative part numbers.
