PEMI2QFN/WT,115

Overview

The PEMI2QFN/WT,115 is a second-order low-pass RC(Pi) EMI filter manufactured by NXP USA Inc. It features two channels with a resistance of 200 Ohms per channel and a total capacitance of 23pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for signal line protection, it provides attenuation of 25dB at frequencies between 800MHz and 3GHz. The device operates within a temperature range of -40°C to 85°C and includes integrated ESD protection capabilities.

Feature Summary

• Integrates RC(Pi) topology for effective high-frequency noise suppression
• Provides dual-channel filtering for differential or parallel signal lines
• Includes built-in electrostatic discharge (ESD) protection circuitry
• Utilizes a small-footprint surface-mount package for space-constrained designs

Applications

• Local Area Network (LAN) interfaces
• Personal Computer System (PCS) data lines
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix '115' against current manufacturer documentation, as this component is scheduled for obsolescence. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics, as standard stock may be limited. Ensure compliance with RoHS3 standards if required for your specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring robust EMI filtering alongside ESD protection for high-speed digital signals. The 200-ohm resistance value suits specific impedance matching requirements different from the 100-ohm variant. Consider the 6-XFDFN package dimensions for PCB layout constraints. Verify thermal performance within the specified operating temperature range during system integration.

Part Context

This part belongs to the PEMIxQFN family of EMI filters designed for protecting sensitive electronic interfaces. It shares architectural similarities with other variants like the PEMI2QFN/RR,115 but differs in resistance and capacitance values. The series is engineered for compact applications where both signal integrity and component protection are critical priorities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the component's discontinued status, engineers should consult official replacement guides or contact the manufacturer directly for validated alternatives.
