NUF4401MNT1G

Overview

The NUF4401MNT1G is a four-channel EMI filter manufactured by onsemi, designed for signal line protection in compact electronic devices. It integrates passive filtering components within a single surface-mount package to suppress electromagnetic interference across multiple data lines simultaneously. The device operates within a temperature range of -40°C to +85°C and provides attenuation of 35dB at frequencies between 900MHz and 2.4GHz. Packaged in a small outline footprint, it supports high-density board layouts while maintaining signal integrity for high-speed interfaces.

Feature Summary

• Integrates four independent filtering channels into a single compact component
• Provides effective suppression of electromagnetic interference across wide frequency bands
• Designed for space-constrained applications requiring multi-line signal protection

Applications

• Portable consumer electronics with multiple high-speed data interfaces
• Mobile communication devices requiring EMI mitigation for RF and baseband signals
• Embedded systems utilizing parallel data buses susceptible to noise interference

Procurement Notes

Verify the current lifecycle status as sources indicate this part may be obsolete or end-of-life. Confirm availability through authorized distributors or check for valid replacement recommendations from onsemi before finalizing procurement plans. Ensure the specific suffix matches required packaging options if reel or cut tape quantities are needed.

Selection Notes

Select this component when designing circuits that require simultaneous EMI filtering for four distinct signal lines within a limited board area. Evaluate the insertion loss characteristics against the specific data rates of the connected interfaces to ensure minimal signal degradation while achieving the necessary noise reduction targets for regulatory compliance.

Part Context

This component belongs to onsemi's portfolio of passive filter solutions aimed at enhancing signal integrity in modern digital systems. It addresses the growing demand for compact, integrated EMI management in portable devices where discrete filter components would consume excessive PCB real estate.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the reported obsolete status. Consult official manufacturer resources for current alternative recommendations.
