Overview
The NUF9001FCT1G is a 10-channel RC Pi-filter EMI filter with integrated ESD protection, manufactured by onsemi. It features a low-pass topology with a cutoff frequency of 100MHz and provides -35dB attenuation between 800MHz and 3GHz. The device incorporates ten channels, each with a resistance of 100 ohms, totaling 45pF capacitance. Packaged in a compact 25-UFBGA (FCBGA) surface-mount format measuring 2.65mm x 2.65mm x 0.65mm, it operates within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates EMI filtering and electrostatic discharge protection for data lines
- Utilizes an RC Pi-filter architecture for effective high-frequency noise suppression
- Designed for space-constrained mobile device applications
Applications
- Data line protection in mobile devices
- High-speed interface signal conditioning
- EMI mitigation in portable electronics
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm package integrity and pin alignment against the 25-UFBGA specification. Ensure compliance with RoHS and REACH requirements as documented in official material declarations. Validate thermal performance within the specified operating range during integration.
Selection Notes
Select this component when simultaneous EMI filtering and ESD protection are required for multiple data lines in a minimal footprint. The 100-ohm impedance matches standard data line characteristics. Consider the 25-UFBGA package constraints for PCB layout. Evaluate the 100MHz cutoff frequency against target signal bandwidths to ensure adequate signal integrity while suppressing interference.
Part Context
This part belongs to the NUF9001 series of multi-line filters from onsemi. It is designed specifically for protecting high-speed data interfaces in consumer electronics. The device consolidates passive filtering and transient protection into a single surface-mount component, reducing bill-of-materials complexity compared to discrete solutions.
Replacement Considerations
NUF9002FCT1G is a documented alternative offering similar low-capacitance 10-line EMI filtering with ESD protection capabilities.
