Overview
The SNUF6401MNT1G is a six-channel EMI filter array with integrated ESD protection, utilizing a C-R-C Pi-filter topology. It features typical component values of R = 100 Ω and C = 17 pF, providing a cutoff frequency of 110 MHz. The device achieves greater than -30 dB attenuation in the 800 MHz to 3.0 GHz range. Packaged in a low-profile 12-pin DFN12 (1.35 mm x 3.0 mm) surface-mount format, it supports data rates up to 74 Mbps for parallel interfaces. Each channel offers ±15 kV ESD protection per IEC61000-4-2 contact discharge standards.
Feature Summary
- Integrated ESD protection capability of ±15 kV per channel ensures robust defense against electrostatic discharge events.
- C-R-C Pi-filter architecture delivers effective high-frequency noise suppression with specified attenuation characteristics.
- Compact DFN12 surface-mount package design facilitates space-efficient PCB layout and improved thermal management.
Applications
- Parallel interface circuits requiring signal integrity maintenance
- Systems needing mitigation of wireless interference
- Data lines operating at speeds up to 74 Mbps
Procurement Notes
Verify the specific suffix 'S' indicates AEC-Q101 qualification and PPAP capability when automotive compliance is required. Confirm the DFN12 package variant matches the design footprint requirements. Ensure RoHS and halogen-free status aligns with environmental regulations. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component for applications demanding simultaneous EMI filtering and ESD protection in a minimal footprint. The 100 Ω resistance and 17 pF capacitance are optimized for preserving signal integrity while attenuating high-frequency noise. Consider the DFN12 package dimensions for board space constraints. Verify that the 110 MHz cutoff frequency meets the specific bandwidth requirements of the target parallel interface application.
Part Context
This device belongs to onsemi's family of integrated EMI/ESD solutions designed for compact electronic systems. It combines passive filtering elements with transient voltage suppression capabilities into a single monolithic structure. The product line targets modern electronics where space savings and multi-functional components are critical for system reliability and performance optimization.
Replacement Considerations
NUF6401MNT1G is a compatible alternative within the same series. SZNUF6401MNWT1G offers a winged lead DFNW12 package for enhanced AOI inspection. Verify pin compatibility and electrical specifications before substituting any variant.
