PEMI6QFN/CR,132

Overview

The PEMI6QFN/CR,132 is a six-channel EMI/RFI filter manufactured by NXP USA Inc. It utilizes an RC Pi-network topology to provide second-order low-pass filtering for multiple signal lines within a single compact package. The component features a total capacitance of 21pF and a resistance of 20 Ohms per channel. Designed for surface-mount applications, it is housed in a 12-XFDFN package, offering efficient space utilization for high-density circuit boards while suppressing electromagnetic interference across the filtered channels.

Feature Summary

• Integrates six independent filtering channels into a single compact surface-mount device
• Employs RC Pi-network topology for effective second-order low-pass signal conditioning
• Optimized for high-density PCB layouts with minimal footprint requirements

Applications

• High-speed digital signal line protection in consumer electronics
• EMI suppression for data interfaces in portable devices
• Signal integrity enhancement in dense multi-channel communication modules

Procurement Notes

Verify current lifecycle status as some sources indicate this product may be scheduled for obsolescence or discontinued by the manufacturer. Confirm availability through authorized distributors and check for valid RoHS3 compliance documentation before procurement. Ensure the specific suffix matches design requirements as variants exist within the family.

Selection Notes

Select this component when multiple signal lines require simultaneous EMI filtering in space-constrained designs. The 20 Ohm resistance and 21pF total capacitance define the cutoff characteristics suitable for general-purpose high-speed data lines. Consider alternative packages if higher pin counts or different thermal profiles are required for the specific application environment.

Part Context

This part belongs to the PEMI6QFN series of integrated EMI filters from NXP Semiconductors (now Nexperia). These components are designed to replace discrete RC networks, reducing board space and assembly complexity. The CR suffix typically denotes specific internal configuration or packaging variations within the broader QFN filter family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs if considering alternatives due to potential obsolescence.
