Overview
The NFZ32BW221HN10L is a surface-mount ferrite bead from the Murata EMIFIL NFZ series, designed for electromagnetic interference suppression. 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 1 MHz with a tolerance of 30%. It supports a maximum DC current of 390 mA and has a maximum DC resistance of 1.38 Ohms. The operating temperature range spans from -40°C to +125°C.
Feature Summary
- Designed to suppress radiation noise in the frequency range starting from 30 MHz
- Utilizes a flat lead SMD/SMT termination style for PCB mounting
- Constructed as a single-line impedance component within the NFZ series
Applications
- Electromagnetic interference filtering in electronic circuits
- Radiation noise suppression applications
- Signal line protection in consumer electronics
Procurement Notes
Verify the specific impedance value against official datasheets, as distributor listings may vary between 200 Ohms and 220 Ohms. Confirm the maximum DC current rating matches design requirements, noting discrepancies between 250 mA and 390 mA in available sources. Ensure the package dimensions and termination type align with the target PCB footprint before ordering.
Selection Notes
Select this component for applications requiring EMI suppression in the 1210 form factor. Consider the 390 mA current rating when designing power or signal lines. The 1.38 Ohm DC resistance impacts voltage drop; verify it fits system constraints. The wide temperature range suits general industrial and commercial environments.
Part Context
This part belongs to the Murata NFZ series of ferrite beads, categorized under EMI Filters and Ferrites. It shares the standard 1210 package size with other variants like the NFZ32BW621HN10L but differs in impedance and current handling characteristics. The series is marketed under the EMIFIL trademark for noise suppression solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Variants within the same series, such as NFZ32BW621HN10L, offer different impedance values and should be evaluated for functional compatibility rather than direct pin-to-pin substitution without circuit analysis.
