NUF8402MNT4G

Overview

The NUF8402MNT4G is an eight-channel RC Pi-type EMI filter with integrated ESD protection, manufactured by onsemi. It operates at a working voltage of 5 V and features a breakdown voltage of 6 V. Each channel utilizes a resistance of 100 Ohms and capacitance of 17 pF, resulting in a cutoff frequency of 105 MHz. The device provides attenuation greater than -35 dB in the 800 MHz to 2.2 GHz range and withstands ±18 kV contact discharge per IEC 61000-4-2 Level 4. It is housed in a compact 16-VFDFN package (4.00 mm x 1.60 mm) with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates eight independent low-pass RC Pi filters with built-in electrostatic discharge protection for comprehensive signal line shielding.
• Provides high-level ESD immunity capable of withstanding ±18 kV contact discharge according to IEC 61000-4-2 standards.
• Delivers significant attenuation in the 800 MHz to 2.2 GHz frequency band to suppress electromagnetic interference.
• Utilizes a low-profile surface-mount package to minimize footprint and simplify board layout.

Applications

• Protection of data lines in mobile devices
• Shielding parallel interfaces with data rates up to 70 Mbps
• Filtering signals for 2G/3G cellular modules
• EMI suppression for GPS, Bluetooth, and WLAN circuits

Procurement Notes

Verify the complete part number including the suffix T4G to ensure correct packaging and compliance specifications. Confirm that the DFN-16 package dimensions align with your PCB land pattern design. Check the datasheet for specific soldering reflow profiles and moisture sensitivity level requirements to prevent handling damage during assembly.

Selection Notes

Select this component when designing systems requiring simultaneous EMI filtering and ESD protection for multiple high-speed data lines. It is appropriate for applications where space constraints prohibit discrete components. Ensure the operating voltage does not exceed 5 V and that the required attenuation meets the specific interference frequencies present in the target environment.
