NFZ32BW6R8HN11L

Overview

The NFZ32BW6R8HN11L is a single-line ferrite bead from the Murata EMIFIL NFZ-B series, designed for EMI suppression in surface-mount applications. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height. The component provides an impedance of 6.8 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 2.5 A and has a maximum DC resistance of 43.2 mOhms. The device operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics at target frequencies.
• Supports high-current operation suitable for power line filtering applications.
• Utilizes a compact surface-mount footprint for efficient PCB space utilization.

Applications

• Power supply output filtering
• High-speed data line noise suppression
• General EMI suppression in consumer electronics

Procurement Notes

Verify the specific suffix HN11L against the official Murata datasheet to confirm impedance and current ratings. Ensure the ordering code matches the required packaging format, such as cut tape or reel, as availability varies by distributor. Cross-reference the manufacturer part number with authorized supplier databases to prevent counterfeit components.

Selection Notes

Select this component when a low impedance value of 6.8 Ohms is required for high-current lines up to 2.5 A. The 1210 package offers a balance between current handling capability and board space. Consider the 30% tolerance and temperature stability if precise attenuation characteristics are critical for the circuit design.

Part Context

This component belongs to the Murata NFZ-B series of EMI suppression filters. The series is characterized by its ability to handle significant DC currents while maintaining small physical dimensions. The NFZ32BW variant specifically utilizes a 3225 metric case size, making it suitable for dense modern electronic assemblies requiring robust noise filtering.

Replacement Considerations

Direct substitutes include other Murata NFZ32BW parts with similar impedance and current ratings, such as NFZ32BW9R8HN11L or NFZ32BW3R3HN11L, provided the impedance difference is acceptable for the application. Verify pin compatibility and thermal performance before substitution.
