PEMI4QFN/CM,132

Overview

The PEMI4QFN/CM,132 is a surface-mount RC (Pi) EMI filter from the NXP PEMIxQFN series. It features a four-channel low-pass configuration designed for second-order attenuation. The component integrates resistors with a value of 20 Ohms and capacitors totaling 16 pF across the channels. It is housed in an 8-XFDFN package.

Feature Summary

• Provides four-channel passive filtering for signal lines
• Utilizes RC Pi-network topology for second-order attenuation
• Designed for surface-mount assembly

Applications

• High-speed data line protection
• Signal integrity enhancement in digital circuits
• EMI suppression on interface ports

Procurement Notes

Verify the specific suffix against official documentation to confirm resistor and capacitor values. Ensure the package type matches the design footprint. Confirm the manufacturer source is NXP USA Inc. or authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact, multi-channel solution is required for EMI reduction. The 20-ohm resistance and 16-pF capacitance define the cutoff frequency characteristics. Consider the XFDFN package size for space-constrained layouts.

Part Context

This part belongs to the PEMIxQFN family of passive filter networks. These components are engineered to replace discrete R and C arrangements, saving board space. The series offers various configurations tailored for different impedance and capacitance requirements.

Replacement Considerations

Check datasheets for parts with identical 20-ohm and 16-pF specifications. Verify pin compatibility and package dimensions before substitution.
