PEMI2QFN/HK,115

Overview

The PEMI2QFN/HK,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 per channel and a total capacitance of 13.5 pF. 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 from 800MHz to 3GHz while offering electrostatic discharge (ESD) protection. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual-channel RC Pi-filter topology for effective common-mode noise suppression on high-speed data lines.
• Provides combined EMI filtering and ESD protection capabilities within a single compact surface-mount footprint.
• Engineered for minimal signal distortion and low insertion loss in sensitive communication interfaces.

Applications

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

Procurement Notes

Verify the specific suffix HK against the official datasheet to confirm the 45-ohm resistance value, as other suffixes in this family may differ. Confirm RoHS compliance status and check for obsolescence notices, as availability varies by region. Ensure the 6-XFDFN package dimensions match your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring integrated ESD protection and EMI filtering for differential or single-ended data lines. The 45-ohm impedance helps maintain signal integrity while attenuating high-frequency noise. Consider the 6-XFDFN package size for space-constrained applications where standard discrete components would exceed board area limits.

Part Context

This part belongs to the PEMIxQFN/2STD family of EMI filters from Nexperia/NXP. These devices are specifically designed to protect sensitive electronic interfaces from electromagnetic interference and electrostatic discharge events. The family offers various resistance values to suit different impedance matching requirements across LAN and WAN applications.

Replacement Considerations

Check for direct substitutes within the PEMI2QFN series with matching 45-ohm resistance and 13.5pF capacitance. Verify pinout compatibility and thermal performance if replacing with components from other manufacturers. Ensure any alternative maintains the same 6-XFDFN package outline for seamless integration.
