NFZ32BW621HN10L

Overview

The Murata NFZ32BW621HN10L is a surface-mount ferrite bead from the EMIFIL NFZ series, designed for EMI suppression in electronic circuits. 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 620 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 2.7 Ohms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high impedance noise filtering for electromagnetic interference suppression
• Designed for surface-mount technology integration on printed circuit boards
• Constructed for reliable operation across extended industrial temperature ranges

Applications

• General EMI noise suppression in electronic circuits
• Signal line filtering for digital interfaces
• Power supply noise attenuation

Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm packaging format and compliance status. 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 authenticity and availability before procurement.

Selection Notes

Select this component when a 620 Ohm impedance at 1 MHz is required for noise reduction. The 250 mA current rating limits suitability for high-power lines. The 1210 footprint offers a balance between size and thermal performance. Verify that the 2.7 Ohm DC resistance does not cause excessive voltage drop in the specific circuit design.

Part Context

This ferrite bead belongs to the Murata EMIFIL NFZ series, which focuses on compact surface-mount solutions for high-frequency noise suppression. The NFZ series is widely used in consumer electronics and industrial equipment where space constraints require small form factors like the 1210 package. It complements other passive components in filter networks.

Replacement Considerations

Direct substitutes include NFZ32BW621HN10K, which shares identical electrical specifications but may differ in packaging configuration. Verify compatibility with existing PCB footprints and soldering profiles when considering alternative suffixes or manufacturers.
