NFZ32BW190HZ11L

Overview

The NFZ32BW190HZ11L is a single-line ferrite bead from Murata Electronics' EMIFIL NFZ32BW series, designed for EMI suppression in the 30 to 150 MHz radiation noise range. It features a 19 Ohm impedance at 100 MHz and a maximum DC resistance of 150 milliohms. The component supports a rated current of 1.6 Amperes and operates within a temperature range of -40°C to +125°C. Housed in a compact 1210 (3.2mm x 2.5mm) surface-mount package with a maximum height of 1.70mm, it utilizes flat lead terminals for PCB integration.

Feature Summary

• Engineered for high-impedance attenuation in the 30 to 150 MHz frequency spectrum
• Compact 1210 footprint enables efficient space-saving circuit board layouts
• Flat lead terminal design facilitates reliable surface-mount assembly processes

Applications

• Suppression of radiated electromagnetic interference in digital signal lines
• Noise filtering for high-speed data transmission interfaces
• EMI mitigation in portable electronic devices and mobile communication modules

Procurement Notes

Verify the specific suffix 'HZ11L' against official Murata documentation to confirm impedance tolerance and termination specifications. Ensure compatibility with standard 1210 footprints during layout. Confirm RoHS3 compliance status for regulatory adherence. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when targeting noise frequencies between 30 and 150 MHz. The 1.6A current rating suits moderate-power signal lines. The 19 Ohm impedance provides effective damping without excessive signal loss. Verify that the 150 milliohm DC resistance aligns with power budget constraints. Ensure the operating temperature range meets environmental requirements.

Part Context

This component belongs to the Murata EMIFIL NFZ32BW family, which specializes in small-package ferrite beads for broadband noise suppression. The series offers various impedance values optimized for different frequency bands. The NFZ32BW190HZ11L specifically addresses mid-range RF interference needs using a standardized 1210 case size common in consumer electronics manufacturing.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Generic ferrite beads may lack the precise impedance curve required for 30-150 MHz suppression. Verify that any substitute matches the 1210 dimensions and 1.6A current rating to maintain thermal performance.
