NFZ5BBW4R5LN10L

Overview

The Murata Electronics NFZ5BBW4R5LN10L is a single-channel chip noise filter from the EMIFIL NFZ series, designed for EMI suppression. It features an impedance of 4.5 Ohms at a test frequency of 1 MHz with a tolerance of 30%. The component supports a maximum DC current of 3.4 A and has a maximum DC resistance of 15 mOhms. It operates within a temperature range of -40°C to +125°C. The physical dimensions are 5 mm in length, 5 mm in width, and 2 mm in height, utilizing SMD/SMT termination.

Feature Summary

• Designed for radiation noise suppression in the 30 to 150 MHz frequency range
• High impedance generation capability for effective EMI filtering
• Low DC resistance to minimize power loss in high-current applications

Applications

• General EMI suppression circuits
• Noise filtering for digital signal lines
• Power supply line noise reduction

Procurement Notes

Verify the specific suffix 'LN10L' against the official Murata datasheet to confirm impedance, current rating, and packaging details. Ensure the ordering part number matches the required impedance value of 4.5 Ohms at 1 MHz. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement.

Selection Notes

Select this component when low impedance (4.5 Ohms) is required for high-current paths up to 3.4 A. The 2020 (5050 metric) package size suits space-constrained designs. Verify that the operating temperature range of -40°C to +125°C meets environmental specifications. Consider the 30% impedance tolerance for circuit design margins.

Part Context

This component belongs to the Murata EMIFIL NFZ series, which focuses on impedance components for radiation noise ranges between 30 and 150 MHz. The NFZ5BBW variant specifically denotes a chip noise filter with 2020 package dimensions. It is categorized under ferrite beads and chips for EMI filtering applications.

Replacement Considerations

Check for direct substitutes within the NFZ5BBW series with matching 4.5 Ohm impedance and 3.4 A current rating. Verify pin compatibility and package dimensions for any alternative ferrite beads.
