NUF4001MUT2G

Overview

The NUF4001MUT2G is a four-channel C-R-C Pi-type EMI filter array integrating electrostatic discharge (ESD) protection. Housed in an 8-pin 1.2x1.8mm UDFN surface-mount package, it utilizes typical component values of R = 100 Ω and C = 13 pF to achieve a cutoff frequency of 150 MHz. The device provides greater than -25 dB attenuation in the 800 MHz to 5.0 GHz band. It supports data rates up to 100 Mbps and offers ±14 kV contact discharge and ±16 kV human body model ESD protection.

Feature Summary

• Integrates EMI filtering and ESD protection within a compact low-profile UDFN8 package
• Provides high attenuation for frequencies between 800 MHz and 5.0 GHz
• Supports parallel interfaces with data rates up to 100 Mbps
• Delivers robust ESD protection meeting IEC61000-4-2 Level 4 standards

Applications

• LCD and camera data lines
• I/O ports and keyboards
• Wireless applications requiring interference suppression for 2G/3G, GPS, Bluetooth, and WLAN signals

Procurement Notes

Verify the specific suffix 'T2G' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance and halogen-free status against current manufacturer declarations. Ensure the UDFN8 footprint matches the PCB design guidelines provided in the official datasheet. Validate that the 100 Ω resistance and 13 pF capacitance values align with the target circuit's impedance requirements.

Selection Notes

Select this component for designs requiring simultaneous signal integrity maintenance and static protection in space-constrained environments. The integrated solution reduces bill-of-materials count by combining separate filter and protection devices. It is suitable for portable electronics where minimizing wireless interference is critical without compromising data transmission speeds on parallel buses.

Part Context

This part belongs to onsemi's NUF series of specialized function ICs designed for signal line protection. It complements other ESD suppressors and TVS diodes in the portfolio by offering combined filtering capabilities. The UDFN8 package variant allows for high-density mounting on printed circuit boards used in mobile and consumer electronic devices.

Replacement Considerations

NUF4001MU is the leaded or non-tape version of the same functional device. Verify pinout compatibility before substitution. No direct cross-model replacements are confirmed in public documentation; alternative solutions require independent electrical validation.
