NFZ32BW151HZ11L

Overview

The NFZ32BW151HZ11L is a single-line ferrite bead chip from the Murata EMIFIL NFZ32BW series, designed for EMI suppression in surface-mount applications. It features a 1210 (3225 metric) package with dimensions of 3.20mm x 2.50mm and a maximum height of 1.70mm. The component provides an impedance of 150 Ohms at 1 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 700mA and has a maximum DC resistance of 570 milliohms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics at target frequencies.
• Utilizes a compact 1210 surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Engineered for stable performance across a wide industrial operating temperature range.

Applications

• High-speed signal line filtering in portable electronic devices
• Power supply noise suppression in embedded systems
• EMI mitigation in automotive electronics modules

Procurement Notes

Verify the specific suffix HZ against official Murata documentation to confirm impedance tolerance and termination specifications. Confirm end-of-life status as some distributors list this part as not recommended for new designs. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number directly with authorized channels to avoid counterfeit components.

Selection Notes

Select this component when a 150 Ohm impedance at 1 MHz is required for noise attenuation. The 700mA current rating dictates suitability for low-to-medium power signal lines rather than high-current power rails. Consider the 1210 package size relative to available PCB real estate. Evaluate thermal dissipation requirements given the 570 milliohm DC resistance under load conditions.

Part Context

This ferrite bead belongs to the NFZ32BW series, which offers various impedance values in a standardized 1210 case size. The series is characterized by high saturation current capabilities and consistent frequency response profiles. It serves as a passive component for differential and single-ended line protection in modern electronic assemblies.

Replacement Considerations

Consult official Murata substitution guides for equivalent impedance and current ratings. Verify that alternative components match the 1210 footprint and terminal configuration. Ensure replacement parts meet the same -40°C to +125°C operating temperature range and RoHS compliance standards.
