PEMI1QFN/CM,315

Overview

The PEMI1QFN/CM,315 is a second-order RC Pi EMI filter manufactured by NXP USA Inc. It features a single channel with an integrated resistance of 20 Ohms and a total capacitance of 16 pF. The component is housed in a compact SOT-883 (SC-101) surface-mount package. Designed for signal conditioning, it provides effective attenuation for high-frequency noise while maintaining low insertion loss. The device is RoHS compliant and suitable for applications requiring reliable EMI suppression in space-constrained environments.

Feature Summary

Integrates a 2nd order RC Pi network for efficient EMI suppression
Includes built-in ESD protection capabilities
Utilizes a compact SOT-883 surface-mount footprint

Applications

Signal conditioning for data lines
EMI filtering in portable electronics
Noise suppression in automotive systems

Procurement Notes

Verify the specific suffix 'CM' against the official NXP datasheet to confirm the exact passive values and package variant. Ensure the source document explicitly identifies this part as currently available or obsolete, as supply status can vary. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the RoHS compliance status matches current regulatory requirements for your target market.

Selection Notes

Select this component when a compact, integrated solution for single-channel EMI filtering is required. The fixed 20 Ohm resistance and 16 pF capacitance are optimized for specific impedance matching scenarios. Consider the SOT-883 package size if board real estate is limited. Evaluate the trade-off between the integrated ESD protection and external protection needs based on system-level requirements.

Part Context

This part belongs to the PEMIxQFN series of passive filter networks from NXP. These components are designed to replace discrete R-C-L arrangements, simplifying PCB layout. The series offers various configurations tailored for different signal integrity needs. This specific model represents a standard RC Pi topology within that family.
