PEMI1QFN/CG,315

Overview

The PEMI1QFN/CG,315 is a single-channel EMI/RFI filter manufactured by NXP USA Inc. It utilizes an RC Pi-filter topology designed for signal conditioning and noise suppression in electronic circuits. The component integrates passive filtering elements with electrostatic discharge (ESD) protection capabilities. It is housed in a compact SOT-883 package, also identified as SC-101 or 3-XQFN, suitable for surface-mount assembly. Key electrical parameters include a resistance of 20 Ohms and a total capacitance of 11 pF, providing second-order low-pass filtering characteristics.

Feature Summary

• Integrates RC Pi-filter network for effective EMI and RFI attenuation
• Includes built-in ESD protection for data line safeguarding
• Compact SOT-883 surface-mount package design

Applications

• Data line filtering in portable electronics
• Signal conditioning for high-speed interfaces
• EMI suppression in consumer devices

Procurement Notes

Verify the manufacturer designation carefully, as this component family is distributed by both NXP Semiconductors and Nexperia. Confirm the specific suffix 'CG,315' matches your bill of materials to ensure correct impedance and capacitance values. Check RoHS compliance status and datasheet revisions before finalizing procurement orders to avoid integration issues.

Selection Notes

Select this component when a single-channel solution with integrated ESD protection is required for space-constrained designs. The 20 Ohm resistance and 11 pF capacitance values define its cutoff frequency and filtering performance. Ensure the SOT-883 footprint aligns with the PCB layout constraints and that the voltage ratings meet the system requirements.

Part Context

This part belongs to the PEMI1QFN series of integrated EMI filters from NXP/Nexperia. Variants within this series differ primarily in the number of channels (1, 4, 6, or 8) and specific electrical parameters such as resistance and capacitance values. The '1' in the model number indicates a single-channel configuration, distinguishing it from multi-channel counterparts like the PEMI4QFN series.

Replacement Considerations

Direct substitutes may include other single-channel RC EMI filters in SOT-883 packages from manufacturers like Nexperia, provided the electrical parameters match. Verify pin compatibility and physical dimensions before substitution.
