PEMI8QFN/HK,132

Overview

The PEMI8QFN/HK,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 surface-mount technology in a 16-XFDFN package with an exposed pad. Electrical specifications include a resistance of 45 Ohms and a total capacitance of 13.5pF per channel.

Feature Summary

• Eight-channel RC Pi network design for EMI suppression
• Second-order low-pass filtering capability
• Compact 16-XFDFN surface-mount package

Applications

• High-speed data line protection
• USB interface filtering
• HDMI signal integrity enhancement
• General purpose EMI reduction in consumer electronics

Procurement Notes

Verify the manufacturer marking against official NXP documentation to confirm authenticity. Ensure the suffix HK corresponds to the specific resistance and capacitance values required for your circuit design. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when multi-channel EMI filtering is required in space-constrained applications. The RC Pi topology offers effective attenuation without introducing significant signal distortion. Consider the thermal performance of the exposed pad if operating in high-power environments or dense layouts.

Part Context

This part belongs to the PEMI series of EMI filters from NXP Semiconductors. These components are designed to meet stringent electromagnetic interference standards for modern digital interfaces. The QFN format allows for efficient board space utilization compared to discrete filter solutions.

Replacement Considerations

Check for direct substitutes within the same family, such as variants with different resistance values or channel counts. Verify that any replacement maintains the same package outline and pinout configuration to ensure drop-in compatibility.
