PEMI2QFN/HT,115

Overview

The PEMI2QFN/HT,115 is a dual-channel RC(Pi) EMI filter and ESD protection device manufactured by Nexperia USA Inc. It features a second-order low-pass configuration with a resistance of 45 ohms per channel and a total capacitance of 23pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.00mm x 1.00mm x 0.50mm. Designed for high-speed data lines, it provides attenuation of 25dB from 800MHz to 3GHz while protecting downstream components from electrostatic discharge voltages.

Feature Summary

• Integrates passive RC filtering with ESD protection diodes in a single compact package
• Provides second-order low-pass filtering characteristics for signal integrity
• Offers dual-channel isolation for independent line protection
• Utilizes a small footprint QFN package with exposed thermal pad for efficient heat dissipation

Applications

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

Procurement Notes

Verify the specific suffix HT against current Nexperia documentation, as product status may have changed. Confirm RoHS compliance and REACH registration details directly with the manufacturer or authorized distributors. Check for obsolescence notices or alternative recommendations if this part is discontinued. Ensure the ordering code matches the exact resistance and capacitance values required for your circuit design.

Selection Notes

Select this component when space constraints require an integrated solution for both ESD protection and high-frequency noise suppression. The 45-ohm resistance value suits specific impedance matching requirements for high-speed digital interfaces. Consider the 23pF total capacitance impact on signal rise times. The XFDFN package is suitable for automated surface-mount assembly processes requiring thermal management via the exposed pad.

Part Context

This device belongs to the PEMIxQFN family of integrated passive filter networks. These components combine multiple functions into minimal footprints, replacing discrete resistor, capacitor, and diode arrays. The family offers various channel counts and package types to accommodate different board space and performance needs in modern electronic designs.
