Overview
The PEMI2QFN/LR,115 is a passive RC Pi-filter network with integrated ESD protection, manufactured by Nexperia USA Inc. (formerly NXP). It features a low-pass topology designed for data line filtering in high-speed interfaces. The component utilizes a compact 6-pin XFDFN package, measuring 1.45mm x 1.00mm x 0.50mm. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards. This device provides signal integrity enhancement while protecting sensitive ports from electrostatic discharge events.
Feature Summary
- Integrates passive RC filter networks with built-in ESD protection capabilities
- Provides low-pass filtering characteristics for data line noise suppression
- Utilizes a compact surface-mount package suitable for space-constrained designs
Applications
- Local Area Network (LAN) port protection
- Personal Computer System (PCS) interface filtering
- Wide Area Network (WAN) data line conditioning
Procurement Notes
Verify the specific suffix LR against official Nexperia documentation to confirm exact electrical tolerances and pinout configuration. Confirm current availability status as previous similar variants have been discontinued. Ensure the selected package matches the PCB footprint requirements for the 6-XFDFN form factor.
Selection Notes
Select this component when designing circuits requiring combined ESD protection and RF interference filtering for differential or single-ended data lines. Evaluate the parasitic capacitance and resistance values against the target data rate specifications. Ensure the operating voltage and current ratings align with the system's power supply constraints.
Part Context
This part belongs to the PEMIxQFN family of integrated passive devices. These components are engineered to replace discrete filter and protection circuits, reducing board space and assembly complexity. The family typically offers multiple channel configurations to support various interface standards.
Replacement Considerations
Check Nexperia datasheets for direct replacements such as PEMI2QFN/RR,115 or PEMI2QFN/HM,115. Verify that substitute parts maintain identical pin assignments and electrical performance metrics before implementation.
