Overview
The NFZ32BW190HN11L is a single-line ferrite bead from the Murata EMIFIL NFZ series, housed in a 1210 (3225 metric) surface-mount package. It provides an impedance of 19 Ohms at 100 MHz with a tolerance of 30%. The component supports a maximum DC current of 1800 mA and features a maximum DC resistance of 89 mOhms. It operates within a temperature range of -40°C to +125°C and has physical dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height.
Feature Summary
- Designed for radiation noise suppression in the 30 to 150 MHz frequency range
- Generates high impedance within a compact surface-mount footprint
- Supports high current ratings suitable for power line filtering applications
Applications
- EMI suppression on power supply lines
- Noise filtering in portable electronic devices
- Signal integrity enhancement in high-speed digital circuits
Procurement Notes
Verify the specific impedance value and current rating against the official Murata datasheet before integration. Confirm that the 1210 package dimensions align with the target PCB layout constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when high current handling is required alongside effective noise suppression in the VHF band. The 1210 case size offers a balance between thermal performance and space efficiency. Consider the 19 Ohm impedance profile for matching specific circuit attenuation needs. Evaluate the low DC resistance to minimize voltage drop and power loss in the signal path.
Part Context
This component belongs to the Murata NFZ32BW series, which specializes in EMI filters for consumer electronics. The series utilizes advanced ferrite materials to achieve high impedance in small packages. It is part of the broader EMIFIL product line focused on noise suppression for modern digital systems.
Replacement Considerations
Check for direct substitutes within the NFZ32BW series with different impedance values if the electrical characteristics do not match the design requirements. Verify pin compatibility and package dimensions for any cross-brand alternatives.
