NFZ32BW451HN10L

Overview

The NFZ32BW451HN10L is a surface-mount ferrite bead from the Murata EMIFIL NFZ series, designed for electromagnetic interference suppression. 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 450 Ohms at 100 MHz with a tolerance of ±30%. It supports a maximum DC current rating of 275 mA and has a maximum DC resistance of 2.74 Ohms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high impedance attenuation for broadband noise suppression in electronic circuits
• Utilizes a compact 1210 surface-mount footprint for efficient PCB space utilization
• Constructed with robust materials ensuring stable performance across wide industrial temperature ranges

Applications

• High-speed digital signal line filtering
• Power supply output noise reduction
• Clock circuit EMI suppression

Procurement Notes

Verify the specific suffix HN10L against official Murata documentation to confirm impedance and current ratings. Ensure the procurement channel sources genuine components to avoid counterfeit risks. Confirm RoHS compliance status matches project requirements. Validate that the supplier provides traceable manufacturing data for quality assurance purposes.

Selection Notes

Select this component when a 450 Ohm impedance at 100 MHz is required for noise control. The 275 mA current rating dictates suitability for low-power signal lines rather than high-current power rails. The 1210 package size offers a balance between thermal dissipation and board real estate constraints compared to smaller footprints.

Part Context

This part belongs to the Murata NFZ32BW series of chip ferrite beads. These components are engineered for general-purpose EMI suppression in portable and industrial electronics. The series utilizes specialized ferrite materials optimized for high-frequency absorption characteristics.

Replacement Considerations

Direct substitutes include other 1210 ferrite beads with 450 Ohms impedance and similar current handling capabilities. Verify physical dimensions and terminal configurations before substitution to ensure mechanical compatibility.
