NUF2116MNT1G

Overview

The NUF2116MNT1G is a two-channel audio EMI filter with integrated ESD protection, manufactured by onsemi. It utilizes an RC PI-filter topology to suppress electromagnetic interference in audio signal lines. The device operates at a working voltage of 5 V and features a low capacitance of 50 pF per channel to preserve signal integrity. Packaged in a compact DFN-8 surface-mount format, it provides bidirectional protection against electrostatic discharge events up to 30 kV (contact discharge). The component supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual-channel RC PI-filter network for effective audio line EMI suppression
• Provides robust electrostatic discharge protection rated for 30 kV contact discharge
• Maintains low parasitic capacitance to ensure minimal signal distortion in high-fidelity audio applications

Applications

• Audio port protection in mobile devices
• ESD and EMI filtering for headphone jack circuits
• Protection for microphone input lines in portable electronics

Procurement Notes

Verify the specific suffix 'T1G' confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package outline matches the required DFN-8 footprint dimensions for PCB layout compatibility. Ensure the ordering quantity aligns with standard reel or cut-tape availability constraints defined by the distributor.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and ESD protection for differential or single-ended audio signals. The low capacitance value makes it suitable for high-speed digital audio interfaces where signal integrity is critical. Compare performance metrics against similar series parts like NUF2114 if higher voltage tolerance is not required.

Part Context

This part belongs to the NUF211x series of audio EMI filters from onsemi. It is designed specifically for consumer electronics where space is limited and signal quality must be maintained. The series offers various configurations tailored for different audio interface standards and protection levels.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as NUF2114MNT1G, ensuring functional equivalence in capacitance and protection ratings before substitution.
