PEMI2QFN/WE,115

Overview

The PEMI2QFN/WE,115 is a second-order low-pass RC Pi-filter designed for EMI suppression in surface-mount applications. Manufactured by NXP USA Inc., this component features two channels with an integrated resistance of 100 ohms per channel and a total capacitance of 21 pF. It is housed in a compact 6-XFDFN package measuring 1.45mm x 1.00mm x 0.50mm. The device provides attenuation of 25dB at frequencies between 800MHz and 3GHz, operating within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates RC Pi-filter topology for effective EMI noise reduction
• Provides dual-channel signal filtering capability
• Includes built-in ESD protection structures
• Utilizes ultra-small XFDFN surface-mount packaging

Applications

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

Procurement Notes

Verify the specific suffix WE against official Nexperia documentation to confirm pinout and electrical characteristics, as suffixes define package variants. Confirm current availability status, as some PEMI2QFN variants are marked obsolete. Ensure the selected variant matches the required thermal and mechanical specifications for the target PCB layout.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering and ESD protection. The 100-ohm resistance and 21pF capacitance values suit high-speed digital lines. Verify that the 6-pin XFDFN footprint aligns with the board design rules and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the PEMIxQFN family of EMI filters from Nexperia. These components combine passive filtering with electrostatic discharge protection in a single small outline package. The family targets portable electronics and data communication interfaces where board real estate is limited and signal integrity is critical.
