Overview
The NFZ32BW3R3HZ11L is a single-line ferrite bead from the Murata EMIFIL NFZ series, designed for EMI suppression in 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 3.3 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 2.9 A and has a maximum DC resistance of 24 mOhms. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides electromagnetic interference suppression through high-impedance characteristics at target frequencies.
- Supports high-current operation suitable for power line filtering applications.
- Utilizes a compact surface-mount footprint for efficient PCB space utilization.
Applications
- General EMI noise suppression in electronic circuits
- Power line filtering for digital systems
- Signal integrity improvement in high-speed data lines
Procurement Notes
Verify the specific suffix 'HZ' against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with standard 1210 footprints during layout. Confirm RoHS compliance status via the latest datasheet before integration into regulated products.
Selection Notes
Select this component when a low-impedance path is required for high-current lines while maintaining basic noise attenuation. Compare the 3.3 Ohm impedance value against circuit requirements to ensure sufficient filtering without excessive voltage drop. Consider the 2.9 A current rating relative to peak operational loads.
Part Context
This part belongs to the Murata NFZ32BW series of chip ferrite beads. The series offers various impedance values within the 1210 package size. The NFZ32BW3R3HZ11L specifically targets applications requiring moderate noise suppression with high current handling capabilities.
Replacement Considerations
Direct substitutes include other 1210 ferrite beads with similar 3.3 Ohm impedance and >2.9 A current ratings. Verify physical dimensions and terminal configurations match the existing footprint. Check impedance-frequency curves for equivalent performance characteristics.
