NUF3101FCT1G

Overview

The NUF3101FCT1G is a low-pass RC Pi-filter EMI/RFI filter manufactured by onsemi. It features ten channels with a resistance of 47 Ohms and 100 Ohms, and a total capacitance of 40pF. The device operates within a temperature range of -40°C to 85°C and has a cutoff frequency of 300MHz. It provides attenuation of -35dB at frequencies between 800MHz and 3GHz. The component is housed in an 8-WFBGA package with dimensions of 2.65mm x 2.65mm x 0.65mm.

Feature Summary

• Integrates ten-channel RC Pi-filter topology for comprehensive signal line protection
• Provides combined ESD protection and high-frequency noise suppression
• Designed for compact surface-mount installation in mobile devices

Applications

• Mobile device data lines
• High-speed interface signal filtering
• ESD protection for communication ports

Procurement Notes

Verify the specific datasheet revision and material composition declaration before integration. Confirm that the 8-WFBGA footprint matches the target PCB layout. Ensure the operating temperature range meets system requirements. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when multi-line EMI filtering and ESD protection are required in a minimal footprint. The integrated RC Pi-network simplifies design compared to discrete components. Verify that the 40pF total capacitance aligns with the impedance matching needs of the specific data lines.

Part Context

This part belongs to the NUF9001 series family of EMI filters from onsemi. It shares similar packaging and functional principles with other members like the NUF9001FCT1G but offers specific channel counts and electrical values tailored for mobile applications.

Replacement Considerations

Check for direct substitutes within the NUF series such as NUF9001FCT1G if channel count and electrical parameters allow. Verify package compatibility and thermal performance before substitution.
