Overview
The NFZ32BW291HZ10L is a single-channel ferrite bead from Murata's EMIFIL NFZ series, designed for surface-mount applications. 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 290 Ohms at 100 MHz with a tolerance of 30%. It supports a maximum DC current of 700 mA and has a maximum DC resistance of 380 mOhms. Operating temperatures range from -40°C to +125°C. The part is AEC-Q200 qualified and RoHS compliant.
Feature Summary
- Provides high-impedance noise suppression in the 290 Ohm range at 100 MHz
- AEC-Q200 qualified for automotive reliability standards
- Supports high DC current loads up to 700 mA
- Operates reliably across extended temperature ranges from -40°C to +125°C
Applications
- Automotive electronic circuit noise filtering
- High-current power line EMI suppression
- Compact SMT designs requiring 1210 footprint
Procurement Notes
Verify the specific suffix HZ10L against official Murata documentation to confirm packaging and tape specifications. Confirm AEC-Q200 qualification status directly with the manufacturer or authorized distributors. Ensure the selected variant matches the required impedance tolerance and current ratings for the target application environment.
Selection Notes
Select this component when a 1210 footprint is required for high-current noise suppression. The 290 Ohm impedance at 100 MHz targets specific frequency bands. Verify that the 700 mA current rating exceeds the circuit's maximum DC load. Consider the 380 mOhms DCR impact on voltage drop. Ensure the operating temperature range meets system requirements.
Part Context
This part belongs to the Murata EMIFIL NFZ series of chip noise filters. These components are engineered for electromagnetic interference suppression in compact electronic assemblies. The NFZ series utilizes specialized ferrite materials to provide effective broadband noise attenuation while maintaining low insertion loss in power lines.
Replacement Considerations
Check for direct substitutes within the NFZ series offering identical 1210 dimensions and 290 Ohm impedance. Verify that any replacement maintains the same AEC-Q200 qualification and 700 mA current handling capability. Ensure thermal and electrical characteristics match the original design constraints.
