NUF6400MNTBG

Overview

The NUF6400MNTBG is a six-channel EMI filter with integrated ESD protection designed for high-speed data lines. It features an RC (Pi) low-pass topology with a cutoff frequency of 35 MHz. The component provides -30 dB attenuation from 800 MHz to 2.4 GHz, effectively suppressing electromagnetic interference in wireless applications. Electrical specifications include a resistance of 100 Ohms and capacitance of 50 pF per channel. It supports a maximum current of 20 mA and operates within a voltage range up to 12 V. The device is housed in a compact 12-lead DFN package.

Feature Summary

• Integrates six-channel EMI filtering with built-in electrostatic discharge protection
• Utilizes RC Pi-network topology for effective second-order low-pass filtering
• Provides significant signal attenuation across the 800 MHz to 2.4 GHz frequency band

Applications

• Wireless communication interface protection
• High-speed data line filtering
• USB and GPIO port surge suppression

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel quantity matches project requirements. Confirm that the DFN-12 package dimensions align with the target PCB footprint. Check for any RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system's thermal design constraints.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required on multiple channels within a limited space. The 35 MHz cutoff frequency suits applications where signal integrity must be maintained above this threshold while attenuating higher-frequency noise. Consider the 100 Ohm resistance value to ensure it does not degrade the DC performance or signal amplitude of the connected circuitry beyond acceptable limits.

Part Context

This part belongs to onsemi’s family of specialized function ICs focused on circuit protection and signal conditioning. It addresses the growing need for compact, multi-channel solutions in portable electronics and IoT devices. The integration of filtering and protection reduces the bill of materials and simplifies layout compared to discrete component implementations.
