NUF6401MNT1G

Overview

The NUF6401MNT1G is a six-channel EMI filter array with integrated electrostatic discharge (ESD) protection, manufactured by onsemi. It utilizes a C-R-C Pi-filter topology per channel, featuring typical component values of R = 100 Ω and C = 17 pF. This configuration yields a cutoff frequency of 110 MHz and provides greater than -30 dB attenuation in the 800 MHz to 3.0 GHz range. The device supports data rates up to 74 Mbps for parallel interfaces. It offers ±15 kV ESD protection compliant with IEC61000-4-2 contact discharge standards. The component is housed in a low-profile 12-pin DFN12/DFNW12 surface-mount package measuring 1.35 mm x 3.0 mm.

Feature Summary

• Integrates six independent EMI filtering channels with built-in ESD suppression capabilities within a single compact footprint.
• Employs a C-R-C Pi-filter architecture to effectively attenuate high-frequency noise while maintaining signal integrity for parallel data lines.
• Provides robust ±15 kV electrostatic discharge protection per channel, ensuring device reliability against static interference events.

Applications

• Parallel interface circuits requiring EMI suppression and signal line protection
• Electronic systems needing mitigation of wireless interference in the 800 MHz to 3.0 GHz spectrum
• Data transmission modules operating at speeds up to 74 Mbps

Procurement Notes

Verify the specific suffix code to confirm the exact package variant, as the base part number may correspond to different physical footprints such as standard DFN or side-wettable flank DFNW configurations. Confirm that the ordered unit matches the required AEC-Q101 qualification status if intended for automotive applications, as this certification applies only to specific prefixed variants rather than the standard consumer-grade NUF6401MNT1G. Ensure compatibility with RoHS and halogen-free requirements during sourcing.

Selection Notes

Select this component when designing parallel interfaces that require simultaneous EMI filtering and ESD protection without increasing board space. The 17 pF capacitance and 100 Ω resistance values are optimized for signals up to 74 Mbps; higher speed serial interfaces may require different capacitance profiles. Consider the DFN12 package dimensions for thermal management and mechanical fit. Verify that the ±15 kV contact discharge rating meets the specific environmental stress requirements of the target application.

Part Context

The NUF6401MNT1G belongs to onsemi's NUF series of EMI filters with integrated ESD protection. These devices are designed to replace discrete components, reducing assembly complexity and cost. The series includes various channel counts and capacitance values tailored for different interface types, such as USB, HDMI, and parallel data buses. This specific model targets high-density consumer electronics where space constraints and signal cleanliness are critical design parameters.

Replacement Considerations

NUF6402MNT1G: Offers four channels instead of six, suitable for narrower interfaces.
