NFZ32BW8R4HN11L

Overview

The NFZ32BW8R4HN11L is a single-line ferrite bead from the Murata EMIFIL NFZ-B series, designed for surface-mount assembly in a 1210 (3225 metric) package. It provides an impedance of 8.4 Ohms at 1 MHz with a tolerance of 30%. The component supports a maximum DC current of 2.4 A and features a maximum DC resistance of 35 mOhms. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Supports high-current applications with a rated maximum DC current of 2.4 A
• Utilizes a compact 1210 surface-mount footprint for efficient PCB layout

Applications

• General-purpose EMI noise filtering in electronic circuits
• Power line filtering for digital signal integrity
• Suppression of high-frequency noise in consumer electronics

Procurement Notes

Verify the specific suffix HN11L against official Murata documentation to confirm package dimensions and termination style. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a low-impedance path is required for high-current lines while maintaining noise suppression capabilities. The 1210 package offers a balance between current handling capacity and board space efficiency. Consider the 8.4 Ohm impedance value relative to the target noise frequency spectrum to ensure effective attenuation without excessive voltage drop under load conditions.

Part Context

This component belongs to the Murata EMIFIL NFZ-B series of ferrite beads. The series is engineered for general-purpose noise suppression in various electronic devices. The NFZ32BW designation indicates a specific impedance and current rating within the broader 1210 form factor family, catering to diverse circuit requirements.

Replacement Considerations

Direct substitutes include other Murata NFZ32BW variants with similar impedance and current ratings, such as NFZ32BW9R8HN11L or NFZ32BW6R8HN11L. Verify that any replacement maintains the same package size, current handling capability, and impedance profile to ensure circuit compatibility.
