NFZ32BW210HZ11L

Overview

The NFZ32BW210HZ11L is a surface-mount ferrite bead from the Murata EMIFIL NFZ series, designed for electromagnetic interference (EMI) suppression in electronic circuits. Housed in a standard 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height, this component provides an impedance of 21 Ohms at a tolerance of 30%. It supports a maximum DC current of 1.8 A and exhibits a maximum DC resistance of 89 mOhms. The device operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation through ferrite material properties
• Supports high-current applications with a rated maximum DC current of 1.8 A
• Features compact surface-mount construction suitable for automated PCB assembly

Applications

• Power supply output filtering
• Battery charger circuit protection
• Portable electronic device signal integrity management
• Energy-efficient system EMI suppression

Procurement Notes

Verify the specific suffix 'HZ' against official Murata documentation to confirm manufacturing details, as suffixes may indicate specific tape-and-reel configurations or material variations. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration. Ensure the selected packaging format matches production line requirements, as availability varies between cut tape and reel formats.

Selection Notes

Select this component when a 21 Ohm impedance value is required for noise suppression in circuits carrying up to 1.8 A. The 1210 package size offers a balance between current handling capability and board space efficiency. Verify that the operating environment remains within the specified -40°C to +125°C range to ensure stable performance and prevent thermal degradation of the ferrite characteristics.

Part Context

This part belongs to the Murata NFZ series of chip ferrite beads, marketed under the EMIFIL trademark. The series is engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The NFZ32BW variant specifically denotes the 1210 footprint family, providing standardized mounting dimensions compatible with widespread SMT placement equipment.
