Overview
The SZNUF4402MNT1G is a four-channel EMI filter with integrated ESD protection, manufactured by onsemi. It utilizes a C-R-C Pi-style topology within an 8-pin VFDFN exposed pad package. The device features typical component values of R = 100 Ohms and C = 12 pF, delivering a cutoff frequency of 151 MHz. It provides stop band attenuation greater than -25 dB from 800 MHz to 3.0 GHz. Designed for parallel interfaces with data rates up to 101 Mbps, it minimizes wireless interference in applications requiring robust signal integrity.
Feature Summary
- Integrates four-channel RC Pi-filter arrays with ESD suppression capabilities
- Provides high stop-band attenuation exceeding -25 dB across the 800 MHz to 3.0 GHz range
- Supports data transmission rates up to 101 Mbps for parallel interfaces
- Minimizes electromagnetic interference and radio frequency noise effectively
Applications
- Parallel interface circuits requiring EMI reduction
- Systems minimizing wireless interference
- High-speed data line protection
Procurement Notes
Verify the specific suffix 'SZ' against official manufacturer documentation to confirm any distinct material or compliance variations compared to standard NUF4402 variants. Confirm current production status as availability may be limited due to lifecycle changes. Ensure the 8-VFDFN package footprint matches the target PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require simultaneous EMI filtering and electrostatic discharge protection for multiple data lines. The low capacitance value of 12 pF per channel preserves signal integrity for high-speed parallel interfaces. Consider the 100-ohm series resistance impact on signal voltage drops during selection.
Part Context
This part belongs to the NUF4402 family of integrated EMI filters produced by onsemi. These devices are engineered to replace discrete passive components, reducing board space and assembly complexity. The integration of ESD protection alongside filtering functions offers a consolidated solution for protecting sensitive digital interfaces from both environmental noise and static discharge events.
Replacement Considerations
The standard NUF4402MNT1G serves as the primary equivalent. Verify if the 'SZ' prefix indicates a specific customer-specific variant or packaging difference before substitution.
