PEMI4QFN/WT,132

Overview

The PEMI4QFN/WT,132 is a surface-mount EMI filter circuit manufactured by NXP USA Inc. It features an RC (Pi) topology configured as a second-order low-pass filter with four independent channels. The component utilizes an 8-XFDFN package and incorporates integrated ESD protection for signal lines. Key electrical parameters include a resistance value of 200 Ohms per channel and a total capacitance of 23 pF across the network.

Feature Summary

• Integrates passive RC filtering with electrostatic discharge protection
• Provides multi-channel noise suppression in a compact footprint

Applications

• High-speed data line interference mitigation
• Portable electronic device signal conditioning
• Consumer electronics EMI compliance

Procurement Notes

Verify the manufacturer designation carefully, as this component appears under both NXP Semiconductors and Nexperia branding due to corporate restructuring. Confirm the specific suffix matches the required 200 Ohm resistance and 23 pF capacitance values. Ensure the package type corresponds to the XFDFN form factor. Check lifecycle status as some sources indicate manufacturing discontinuation.

Selection Notes

Select this component when designing circuits requiring combined EMI attenuation and ESD robustness for multiple differential or single-ended lines. The 200 Ohm resistance and 23 pF capacitance define the cutoff frequency characteristics suitable for high-speed interfaces. Evaluate the thermal performance and physical dimensions of the XFDFN package against board space constraints.

Part Context

This part belongs to the PEMI4QFN family of passive filter networks from NXP. Variants within this series differ primarily in resistance and capacitance values to target specific frequency bands. The /WT suffix specifically denotes the 200 Ohm/23 pF configuration. Other siblings like PEMI4QFN/RR offer different impedance profiles for alternative application requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other PEMI4QFN variants such as PEMI4QFN/RE,132 or PEMI4QFN/HM,132 only if their respective resistance and capacitance values align with the design specifications.
