PEMI8QFN/CK,132

Overview

The PEMI8QFN/CK,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration with eight channels. The component utilizes a resistance of 20 Ohms and a total capacitance of 13.5 pF. It is housed in a 16-XFDFN package with an exposed pad, designed for surface-mount technology.

Feature Summary

• Eight-channel RC Pi-filter topology for multi-line signal conditioning
• Second-order low-pass filtering characteristic for enhanced attenuation
• Integrated passive components within a compact surface-mount footprint

Applications

• High-speed data line protection in consumer electronics
• EMI suppression on USB or HDMI interfaces
• Signal integrity enhancement in portable devices

Procurement Notes

Verify the exact suffix CK against the manufacturer's current datasheet to confirm pinout and electrical tolerances. Ensure the 16-XFDFN package dimensions match the PCB layout requirements. Confirm RoHS compliance status through official documentation before integration into production.

Selection Notes

Select this component when multi-channel EMI filtering is required in space-constrained designs. The integrated RC structure reduces board space compared to discrete components. Verify that the 20 Ohm resistance and 13.5 pF capacitance values align with the target frequency cutoff requirements for the specific application lines.

Part Context

This part belongs to the PEMIxQFN series from NXP Semiconductors. These components are specialized EMI/RFI filters designed to suppress noise on high-speed digital interfaces. The QFN packaging allows for efficient thermal dissipation and reliable surface mounting in modern electronic assemblies.

Replacement Considerations

Check for direct substitutes within the PEMI8QFN family with different suffixes such as CP or CR, which may offer variations in tolerance or material composition. Ensure any replacement maintains the 20 Ohm resistance and 13.5 pF capacitance specifications.
