NUF2450MUT2G

Overview

The NUF2450MUT2G is a dual-line EMI filter with integrated ESD protection manufactured by onsemi. It utilizes an LC Pi-filter topology to provide third-order low-pass filtering for high-speed data lines. The device features a capacitance of 240pF and an inductance of 2.3nH per line, supporting frequencies up to 5GHz. Packaged in an 8-pin UDFN (UDFN8) surface-mount configuration with an exposed pad, it is designed for compact applications requiring signal integrity and surge protection.

Feature Summary

• Integrates EMI filtering and electrostatic discharge protection within a single component
• Employs LC Pi-filter architecture for effective high-frequency noise attenuation
• Optimized for preserving signal integrity in high-speed digital interfaces

Applications

• USB data line protection
• GPIO interface shielding
• Audio line surge suppression

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Confirm lifecycle status as sources indicate potential obsolescence. Ensure the UDFN8 footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required for dual-channel high-speed signals. The 240pF capacitance value suits applications where minimal signal distortion is critical. Evaluate the 2.3nH inductance against the specific frequency response needs of the target interface.

Part Context

This part belongs to onsemi's lineup of passive components focused on signal conditioning and protection. It addresses the growing need for compact, multi-functional solutions in portable electronics and consumer devices where space constraints limit the use of separate filter and protection devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative LC filters or TVS diodes based on specific circuit impedance and voltage ratings.
