NUF2240W1T1G

Overview

The NUF2240W1T1G is a surface-mount EMI filter with integrated ESD protection, manufactured by onsemi. It features a PI-filter topology designed for two-line applications. The component incorporates RC networks with a resistance of 100 Ohms and capacitance of 17 pF per line. It is housed in an SMD package compliant with RoHS standards. This device provides signal integrity maintenance while suppressing electromagnetic interference and protecting sensitive interfaces from electrostatic discharge events.

Feature Summary

• Integrates dual-line EMI filtering with electrostatic discharge protection capabilities
• Utilizes a compact surface-mount design to minimize circuit board footprint
• Employs a PI-filter architecture combining resistive and capacitive elements for noise suppression

Applications

• High-speed data interface protection
• Portable electronic devices requiring EMI reduction
• Consumer electronics with sensitive input/output ports

Procurement Notes

Verify the specific datasheet revision and mechanical dimensions against your PCB layout requirements before integration. Confirm that the 100 Ohm resistance and 17 pF capacitance values align with your target frequency response and impedance matching needs. Ensure the selected package variant matches your assembly process specifications and environmental operating conditions.

Selection Notes

Select this component when simultaneous EMI attenuation and ESD protection are required for dual-channel signals. The integrated PI-filter structure simplifies bill-of-materials compared to discrete solutions. Evaluate the trade-off between the inherent series resistance and signal loss for high-speed data lines to ensure compliance with system performance standards.

Part Context

This part belongs to onsemi's portfolio of standard semiconductor products focused on signal integrity and protection. It addresses the growing demand for compact, multi-functional components in space-constrained consumer and industrial electronics. The device supports designs aiming to meet regulatory emissions standards while safeguarding internal circuitry from external electrical disturbances.

Replacement Considerations

Distributor records indicate this product may be no longer manufactured. Verify current availability through authorized channels or Rochester Electronics. Identify alternative EMI filters with similar PI-filter topologies, comparable 100 Ohm/17 pF characteristics, and compatible surface-mount packaging if direct substitution is necessary.
