NFZ5BBW141LZ10L

Overview

The NFZ5BBW141LZ10L is a single-channel chip noise filter from the Murata EMIFIL NFZ series, designed for surface-mount applications. It features an impedance of 140 Ohms at a test frequency of 1 MHz with a tolerance of 30%. The component supports a maximum DC current of 1.05 A and exhibits a maximum DC resistance of 259 mOhms to 311 mOhms depending on specific batch documentation. It operates within a temperature range of -40°C to +125°C or +105°C as per varying datasheets. The physical dimensions are 5 mm in length, 5 mm in width, and 2 mm in height, conforming to the 2020 (5050 metric) package standard.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance ferrite characteristics at specified frequencies.
• Engineered with robust construction to withstand soldering heat processes during assembly.
• Designed for automotive reliability standards including AEC-Q200 qualification.

Applications

• Automotive audio line noise filtering
• General electronic circuit EMI suppression
• Power supply line noise reduction

Procurement Notes

Verify the specific operating temperature rating, as sources indicate variations between +105°C and +125°C. Confirm the exact maximum DC resistance value against the latest manufacturer datasheet, as values range from 259 mOhms to 311 mOhms across different documentation versions. Ensure the selected packaging type matches production requirements.

Selection Notes

Select this component when a 140 Ohm impedance at 1 MHz is required for noise attenuation. The 1.05 A current rating suits moderate power lines. The 2020 package size offers a compact footprint for space-constrained designs. Verify thermal limits align with the specific application environment before integration.

Part Context

This part belongs to the Murata NFZ5BBW series of chip noise filters. These components are widely used in automotive and industrial electronics for signal integrity management. The series is characterized by its ability to suppress high-frequency noise while maintaining low insertion loss for desired signals.

Replacement Considerations

Direct substitutes require matching 140 Ohm impedance at 1 MHz, 1.05 A current rating, and 2020 package dimensions. Verify thermal performance and AEC-Q200 compliance if automotive use is intended. Cross-reference with other manufacturers offering equivalent ferrite bead specifications.
