NUF4211MNT1G

Overview

The NUF4211MNT1G is a four-channel EMI filter with integrated ESD protection, manufactured by onsemi. It utilizes a C-R-C Pi-type topology within an 8-pin DFN-2x2mm surface-mount package. Key electrical parameters include a 5 V operating voltage, 6 V breakdown voltage, and 11 pF diode capacitance. The device offers ±8 kV contact discharge ESD protection per IEC 61000-4-2 Level 4. It features a typical cutoff frequency of 250 MHz and provides greater than -20 dB attenuation in the 800 MHz to 3.0 GHz range.

Feature Summary

• Integrates four-channel EMI filtering with electrostatic discharge protection in a single compact component.
• Provides robust ESD immunity meeting IEC 61000-4-2 Level 4 contact discharge standards.
• Utilizes a low-profile DFN-8 package to minimize footprint and support high-density board layouts.

Applications

• EMI filtering for LCD and camera data lines
• Protection for I/O ports and keyboard interfaces
• Data bus protection in portable electronic devices

Procurement Notes

Verify the specific suffix MNT1G against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives and check for any recent lifecycle notifications or obsolescence warnings from onsemi before finalizing procurement plans.

Selection Notes

Select this component when space constraints require combining EMI suppression and ESD protection functions. It is suitable for parallel interfaces requiring data rates up to 167 Mbps. Consider the 11 pF capacitance and 250 MHz cutoff frequency to ensure signal integrity is maintained for the target application bandwidth.

Part Context

This part belongs to onsemi's NUF series of transient voltage suppression diodes and EMI filters. These components are designed to address electromagnetic interference and electrostatic discharge challenges in modern electronics. The series emphasizes integration to reduce bill-of-materials costs and simplify PCB layout processes.

Replacement Considerations

NUF6402MNT1G is a related four-channel EMI filter with ESD protection but uses a DFN-12 package and has different capacitance characteristics. Verify pinout compatibility and electrical parameter alignment before substituting.
