Overview
The NFZ32BW221HZ10L is a single-channel ferrite bead from the Murata EMIFIL NFZ series, designed for surface-mount technology. 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 220 Ohms at a test frequency of 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 electromagnetic interference suppression through high-impedance characteristics in the noise frequency spectrum.
- Utilizes a compact 1210 surface-mount footprint suitable for dense circuit board layouts.
- Engineered for stable performance across a wide industrial temperature range.
Applications
- General-purpose EMI filtering in electronic circuits
- Noise suppression on signal lines requiring moderate current handling
- Power line filtering for low-current digital components
Procurement Notes
Verify the complete part number including suffixes such as HZ10L against official Murata documentation to ensure correct packaging and specifications. Confirm RoHS compliance status via the manufacturer datasheet. Cross-reference the Mouser or distributor catalog numbers to validate authenticity and avoid counterfeit components during sourcing.
Selection Notes
Select this component when a 220 Ohm impedance at 1 MHz is required for noise attenuation. Ensure the circuit current does not exceed the 250 mA rating to prevent saturation. The 1210 package size must fit the available PCB real estate. Consider the 2.7 Ohm DC resistance impact on voltage drop if used in power delivery paths.
Part Context
This ferrite bead belongs to the NFZ series, which offers various impedance values and current ratings in standard SMD packages. It serves as a passive component for suppressing high-frequency noise in consumer and industrial electronics. The NFZ series is distinct from Murata's BLM series by its specific packaging and parameter configurations.
Replacement Considerations
Direct substitutes include other Murata NFZ32BW variants with matching 220 Ohm impedance and 1210 package, such as NFZ32BW221HN10L, provided current ratings and tolerances align with design requirements.
