PEMI4QFN/RK,132

Overview

The PEMI4QFN/RK,132 is a second-order low-pass RC (Pi) EMI filter circuit manufactured by NXP USA Inc. It features four independent channels designed for surface-mount applications in the 8-XFDFN package. The component utilizes passive filtering technology with a resistance value of 100 Ohms and a total capacitance of 13.5 pF per channel to suppress electromagnetic interference.

Feature Summary

• Provides multi-channel EMI suppression using passive RC Pi-network topology
• Designed for high-density surface-mount integration
• Integrates low-pass filtering characteristics within a compact footprint

Applications

• High-speed data line protection
• Portable electronic device signal conditioning
• Consumer electronics interface filtering

Procurement Notes

Verify the specific suffix 'RK' against the target design requirements, as this code defines the unique electrical parameters including the 100 Ohm resistance and 13.5 pF capacitance values. Confirm that the 8-XFDFN package dimensions align with the PCB layout constraints. Ensure compatibility with the intended operating environment and signal frequencies before finalizing procurement decisions.

Selection Notes

Select this component when a quad-channel solution is required for space-constrained designs. The 100 Ohm resistance and 13.5 pF capacitance combination offers specific attenuation characteristics suitable for general-purpose high-speed interfaces. Consider the XFDFN package for its small outline profile compared to larger filter arrays.

Part Context

This part belongs to the PEMIxQFN series from NXP Semiconductors, which provides various configurations of passive EMI filters.
