PEMI4QFN/HE,132

Overview

The PEMI4QFN/HE,132 is a passive EMI filter circuit manufactured by NXP USA Inc. It utilizes an RC (Pi) topology configured as a second-order low-pass filter with four independent channels. The component integrates Electrostatic Discharge (ESD) protection capabilities within the filter network. It is housed in an 8-XFDFN surface-mount package, designed for compact electronic applications requiring signal integrity maintenance.

Feature Summary

• Integrates RC Pi-filter networks with ESD protection
• Provides multi-channel signal filtering
• Designed for high-density surface-mount assembly

Applications

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

Procurement Notes

Verify the specific suffix and tape-and-reel quantity against official NXP documentation before ordering. Confirm that the 8-XFDFN package dimensions match the target PCB footprint. Ensure the selected variant meets the required ESD performance standards for the intended application environment.

Selection Notes

Select this component when a compact solution combining EMI suppression and ESD protection is required. The four-channel configuration supports multiple data lines simultaneously. Verify that the internal resistance and capacitance values align with the system's impedance matching requirements.

Part Context

This part belongs to the PEMI4QFN family of integrated EMI filters. These components are engineered to replace discrete filter and protection circuits, reducing board space and assembly complexity. The family offers various configurations tailored for different interface speeds and channel counts.

Replacement Considerations

Direct substitutes include other variants within the PEMI4QFN series, such as PEMI4QFN/CM,132 or PEMI4QFN/HM,132, provided their electrical parameters match the design requirements. Cross-reference datasheets to ensure compatibility.
