Overview
The NUF4210MNT1G is a unidirectional EMI and RFI filter with four channels, manufactured by onsemi. It operates at a working voltage of 5 V and features a breakdown voltage of 6 V. The device utilizes an 8-VFDFN package with an exposed pad. Key electrical parameters include a diode capacitance of 8.5 pF per channel and a resistance of 100 Ohms. It provides electrostatic discharge protection up to 8 kV. The component functions as a second-order low-pass RC (Pi) filter. It supports surface mount technology and operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Integrates four-channel low-pass filtering for simultaneous data line protection
- Combines ESD suppression with high-frequency noise attenuation in a single compact footprint
- Provides robust transient voltage suppression capabilities for sensitive interfaces
Applications
- Protection for USB data lines in mobile devices
- EMI filtering for GPIO interfaces
- Signal integrity enhancement for audio lines
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status before integration. Confirm that the 8-VFDFN package dimensions match the target PCB land pattern. Ensure the 5 V operating voltage aligns with the system's signal levels. Check for any recent product change notices regarding assembly sites or material composition updates from onsemi.
Selection Notes
Select this component when designing circuits requiring combined ESD protection and EMI filtering for multiple differential or single-ended lines. The low capacitance value preserves signal integrity at high frequencies. Consider the thermal performance of the exposed pad for heat dissipation if applicable. Evaluate the trade-off between insertion loss and attenuation requirements for the specific application bandwidth.
Part Context
This part belongs to onsemi's NUF series of integrated EMI filters and ESD protectors. These components are designed to replace discrete LC networks, saving board space. The series targets portable electronics where size constraints are critical. Similar parts in the family may vary in channel count or capacitance values.
Replacement Considerations
NUF4211MNT1G offers similar functionality but with different capacitance characteristics. Verify pin compatibility and electrical parameter alignment before substitution. Consult official cross-reference guides for validated alternatives.
