PEMI2QFN/LP,115

Overview

The PEMI2QFN/LP,115 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features two channels with a resistance of 65 ohms per channel and a total capacitance of 18.5 pF. The component provides integrated ESD protection and is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for data line filtering, it operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates RC Pi-filter topology for effective EMI suppression
• Includes built-in electrostatic discharge protection circuitry
• Supports dual-channel signal processing in a minimal footprint

Applications

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

Procurement Notes

Verify the specific suffix LP against the official datasheet to confirm the 65-ohm resistance value, as other suffixes in the family denote different impedances. Confirm RoHS3 compliance status and check for obsolete status notifications from Nexperia or NXP before finalizing procurement plans.

Selection Notes

Select this component when a 65-ohm characteristic impedance is required for high-speed data lines. Ensure the 18.5pF total capacitance meets the bandwidth requirements of the application. Verify that the XFDFN package dimensions fit the available PCB real estate constraints.

Part Context

This part belongs to the PEMIxQFN family of EMI filters designed for protecting sensitive electronic interfaces. These components combine passive filtering with active ESD protection to safeguard data lines against both electromagnetic interference and static discharge events in consumer and industrial electronics.

Replacement Considerations

Check for PEMI2QFN/RR,115 if a 100-ohm resistance is acceptable instead of 65 ohms. Verify electrical compatibility with any direct substitutes from Nexperia or NXP before implementation.
