NFZ5BBW4R5LZ10L

Overview

The NFZ5BBW4R5LZ10L is a single-channel ferrite bead from the Murata EMIFIL NFZ series, designed for surface mount applications. It features a 2020 (5050 metric) package with dimensions of 5 mm length, 5 mm width, and 2 mm height. The component exhibits an impedance of 4.5 Ohms at a test frequency of 1 MHz, with a tolerance of 30%. It supports a maximum DC current of 3.4 A and has a maximum DC resistance of 15 mOhms. The device operates within a temperature range of -40°C to +125°C and contains two elements.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies.
• Supports high direct current loads up to 3.4 Amperes without saturation.
• Utilizes a compact 2020 surface-mount footprint for efficient board space utilization.

Applications

• Power supply line filtering in electronic devices
• Noise suppression on data bus lines
• EMI mitigation in automotive electronics

Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance and current ratings. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Check manufacturer specifications for recommended soldering profiles to prevent thermal damage during assembly processes.

Selection Notes

Select this component when low impedance at DC is required alongside moderate noise attenuation. The 3.4 A rating suits power distribution paths where minimal voltage drop is critical. Ensure the operating environment stays within the specified -40°C to +125°C range for reliable performance.

Part Context

This ferrite bead belongs to the NFZ5BBW series, which offers various impedance options in a standardized 2020 package. The series is engineered for general-purpose EMI suppression in consumer and industrial electronics, providing consistent performance across different manufacturing batches.

Replacement Considerations

Substitutes must match the 2020 package size, 4.5 Ohm impedance at 1 MHz, and minimum 3.4 A current rating. Verify that alternative components meet the same DC resistance and temperature specifications to maintain circuit integrity.
