PEMI4QFN/CK,132

Overview

The PEMI4QFN/CK,132 is a four-channel RC Pi-filter EMI filter manufactured by NXP USA Inc. It is housed in an 8-XFDFN surface-mount package. The component features a resistance of 20 Ohms per channel and a total capacitance of 13.5 pF. It provides attenuation of 10 dB at frequencies between 800 MHz and 3 GHz. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Four-channel configuration for simultaneous signal line protection
• RC Pi-filter topology for effective EMI suppression
• Compact 8-XFDFN surface-mount packaging

Applications

• Local Area Network (LAN) interfaces
• Personal Computer System (PCS) data lines
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix CK against official NXP documentation to confirm the 20-ohm resistance value. Ensure the XFDFN package dimensions match the target PCB footprint. Confirm the operating temperature range meets system requirements. Check for RoHS compliance status in the latest datasheet revision.

Selection Notes

Select this component when four independent channels require EMI filtering with low insertion loss. The 20-ohm resistance suits high-speed digital signals where minimal voltage drop is critical. The compact package aids in dense board layouts. Verify compatibility with signal impedance and frequency spectrum before integration.

Part Context

This part belongs to the PEMI4QFN series of integrated EMI filters from NXP. These components are designed to suppress electromagnetic interference on high-speed data lines. The series offers various resistance values to suit different signal integrity requirements while maintaining a small form factor.

Replacement Considerations

Check for direct substitutes with identical 20-ohm resistance and 13.5 pF capacitance. Verify pinout compatibility for the 8-XFDFN package. Ensure equivalent attenuation characteristics in the 800 MHz to 3 GHz range.
