PEMI2QFN/WR,115

Overview

The PEMI2QFN/WR,115 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features two channels with an internal resistance of 200 Ohms per channel and a total capacitance of 21 pF. The component provides attenuation of 25 dB from 800 MHz to 3 GHz. It is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for operation between -40°C and 85°C, it integrates ESD protection diodes to safeguard downstream components.

Feature Summary

• Integrates RC Pi network topology for effective second-order low-pass filtering
• Includes built-in ESD protection diodes for downstream component safety
• Compact 6-lead XFDFN surface-mount package design

Applications

• Local Area Network (LAN) interfaces
• Personal Computer Systems (PCS)
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific ordering suffix 'WR' against official Nexperia/NXP documentation to confirm the 200 Ohm resistance value, as suffixes define electrical parameters. Confirm RoHS3 compliance status and check for active production or obsolescence notices prior to procurement. Ensure the 6-XFDFN footprint matches the target PCB layout requirements.

Selection Notes

Select this component when designing circuits requiring integrated EMI suppression and ESD protection in space-constrained environments. The 200 Ohm resistance and 21 pF capacitance values are optimized for high-frequency signal lines. Consider the 6-lead XFDFN package dimensions for compatibility with dense surface-mount assembly processes.

Part Context

This device belongs to the PEMIxQFN family of EMI filters designed for data line protection. It combines passive filtering elements with electrostatic discharge protection structures within a single small outline package. The series targets applications where signal integrity and component protection are critical constraints.
