NUF2222FCT1G

Overview

The NUF2222FCT1G is a dual-line EMI filter and ESD protection device manufactured by onsemi. It integrates an RC(PI) network with specified component values of 33 Ohms resistance and 36 picofarads capacitance. Designed for surface mount technology, the component utilizes an 8-WFBGA package configuration. The device provides electromagnetic interference filtering and electrostatic discharge protection specifically tailored for USB 1.1 upstream applications.

Feature Summary

• Integrates RC(PI) filtering network for signal integrity
• Provides electrostatic discharge protection capabilities
• Optimized for USB 1.1 upstream interface lines

Applications

• USB 1.1 upstream port protection
• Electromagnetic interference suppression in data lines
• ESD protection for peripheral interfaces

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the 8-WFBGA footprint matches the design layout requirements. Check for any obsolescence notices or lifecycle status updates from onsemi prior to finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring combined EMI filtering and ESD protection for USB 1.1 upstream connections. The integrated 33 Ohm and 36 pF values are fixed; ensure these parameters align with the target impedance and bandwidth requirements of the application without needing external discrete components.

Part Context

This part belongs to onsemi's portfolio of passive filtering and protection devices. It serves as a specialized solution for high-speed digital interfaces where signal integrity and robustness against electrical overstress are critical. The integration of filtering and protection into a single small outline package aids in reducing overall board space consumption.
