Overview
The NUF8401MNT4G is an eight-channel RC Pi-type EMI filter with integrated ESD protection, manufactured by onsemi. It features a typical resistance of 100 ohms and capacitance of 12 pF per channel, providing a cutoff frequency of 175 MHz. The device offers attenuation greater than -25 dB in the 800 MHz to 2.2 GHz range. It is housed in a compact 16-VFDFN package with bare pad, measuring 4.00 mm x 1.60 mm x 1.00 mm. Designed for mobile device data lines, it supports parallel interfaces up to 117 Mbps while mitigating interference from wireless signals.
Feature Summary
- Integrates EMI filtering and electrostatic discharge protection into a single compact surface-mount package
- Provides low-pass filtering characteristics suitable for high-speed data line protection
- Utilizes a small footprint DFN16 package to minimize board space consumption
Applications
- LCD and camera data lines in mobile devices
- I/O ports and keyboard interfaces
- Parallel interface data lines requiring EMI suppression
Procurement Notes
Verify the complete part number including suffixes such as T4G against official manufacturer documentation to ensure correct packaging and environmental compliance specifications. Confirm that the specific ordering code matches the required tape and reel configuration for automated assembly processes. Cross-reference the component marking with datasheet images to prevent counterfeit substitution during procurement.
Selection Notes
Select this component when designing circuits that require simultaneous EMI suppression and ESD protection for multiple data lines within a limited area. The 100-ohm series resistance and 12-pF shunt capacitance are optimized for preserving signal integrity on parallel buses operating at speeds up to 117 Mbps. Ensure the application environment operates within the specified temperature range of -40°C to 85°C for reliable performance.
Part Context
This component belongs to the NUF8401 family of integrated EMI filters produced by onsemi. These devices are engineered specifically for portable electronics where space constraints and signal integrity are critical. The NUF8401MN variant serves as the base model for this surface-mount solution, offering a consolidated approach to noise reduction and static protection compared to discrete component implementations.
Replacement Considerations
NUF8402MNT4G is a related eight-channel EMI filter with ESD protection from the same manufacturer. Verify pin compatibility and electrical parameter differences before substitution.
