Overview
The NFZ32BW7R4HN10L 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 a nominal impedance of 7.4 Ohms at 1 MHz with a tolerance of ±30%. It supports a maximum DC current of 2.05 A and exhibits a maximum DC resistance of 45 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 loads suitable for power line filtering applications
- Utilizes a compact surface-mount footprint for automated assembly integration
Applications
- Power supply output filtering
- DC-DC converter noise suppression
- General EMI suppression on signal lines
Procurement Notes
Verify the specific suffix 'HN10L' against official Murata documentation to confirm packaging configuration and compliance status. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a low-impedance path is required alongside moderate noise suppression capabilities. The 2.05 A current rating makes it appropriate for powering sensitive digital logic or analog sections where minimal voltage drop is critical compared to higher-impedance alternatives.
Part Context
This part belongs to the Murata NFZ series of chip ferrite beads, which are widely used for EMI suppression in portable devices and industrial electronics. The 1210 package size offers a balance between current handling capacity and board space efficiency, fitting into standard SMD manufacturing workflows.
Replacement Considerations
Consult official Murata substitution guides for verified equivalents. Generic cross-references may not match the specific impedance curve or thermal characteristics required for reliable operation.
