PEMI4QFN/HP,132

Overview

The PEMI4QFN/HP,132 is a passive 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 integrates resistors of 45 Ohms and capacitors totaling 18.5 pF per channel. It is housed in an 8-XFDFN surface-mount package designed for compact electronic assemblies.

Feature Summary

• Integrates four-channel RC Pi-filter networks for simultaneous signal line protection
• Provides second-order low-pass filtering characteristics to attenuate high-frequency noise
• Includes integrated ESD protection capabilities within the filter structure

Applications

• High-speed data interface noise suppression
• Portable device signal integrity enhancement
• Consumer electronics EMI mitigation

Procurement Notes

Verify the specific suffix '132' against official NXP documentation to confirm pinout and electrical tolerances. Confirm current lifecycle status as sources indicate this part may be obsolete. Ensure the 8-XFDFN footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when multi-channel EMI filtering is required in space-constrained designs. The integrated nature reduces board space compared to discrete components. Verify that the 45-ohm resistance and 18.5-pF capacitance values align with the target signal frequency specifications.

Part Context

This part belongs to the PEMIxQFN series from NXP, which offers various resistor and capacitor combinations for different filtering needs. It serves as a specialized passive component within the broader portfolio of EMI/RFI filters designed for modern digital systems requiring robust signal cleanliness.

Replacement Considerations

Consult NXP datasheets for alternative suffixes such as PEMI4QFN/LK or PEMI4QFN/RR if different resistance or capacitance values are required. Verify compatibility with existing PCB footprints when considering substitutes.
