PEMI2QFN/HP,115

Overview

The PEMI2QFN/HP,115 is a second-order low-pass RC(Pi) EMI filter manufactured by NXP USA Inc. It features two channels with a resistance of 45 Ohms and a total capacitance of 18.5pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. It provides an attenuation value of 25dB at frequencies between 800MHz and 3GHz. Designed for operation within a temperature range of -40°C to 85°C, it integrates ESD protection capabilities suitable for high-speed data line applications.

Feature Summary

• Integrates RC(Pi) topology for effective second-order low-pass filtering
• Provides integrated electrostatic discharge (ESD) protection
• Utilizes a compact 6-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 suffix '115' against official Nexperia/NXP documentation to confirm the 45 Ohm resistor and 18.5pF capacitor configuration. Confirm RoHS3 compliance status as required by project specifications. Check current product lifecycle status, as this component may be subject to discontinuation notices or production changes documented in public PCNs. Ensure the 6-XFDFN footprint matches the target PCB layout constraints.

Selection Notes

Select this component when a dual-channel EMI filter with moderate impedance (45 Ohms) is required for signal integrity preservation. The 18.5pF total capacitance offers a balance between filtering performance and signal distortion for specific data rates. The small 6-XFDFN package is ideal for space-constrained designs where standard ESD diodes are insufficient for high-frequency noise suppression. Verify compatibility with the target interface voltage levels and current requirements.

Part Context

This device belongs to the PEMIxQFN family of EMI filters from Nexperia (formerly NXP Semiconductors). These components are specifically engineered to suppress electromagnetic interference on high-speed digital lines while providing transient voltage suppression. The QFN packaging allows for efficient thermal dissipation and minimal parasitic inductance compared to traditional leaded packages.
