PEMI1QFN/WR,315

Overview

The PEMI1QFN/WR,315 is an EMI/RFI filter manufactured by NXP USA Inc. It functions as a second-order RC Pi network designed for surface mount applications. The component suppresses electromagnetic interference in high-frequency circuits. It features a compact SOT883 package with a 3-XQFN configuration. The device operates within standard industrial temperature ranges and complies with RoHS3 specifications.

Feature Summary

• Compact second-order RC Pi network design
• Surface mount technology compatibility
• Electromagnetic interference suppression capability

Applications

• High-frequency circuit noise reduction
• Signal integrity enhancement in sensitive electronics
• EMI mitigation in consumer devices

Procurement Notes

Verify the specific suffix WR against the official NXP datasheet to confirm the exact resistance and capacitance values required for the application. Ensure the SOT883 package footprint matches the PCB layout. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a low-profile, second-order passive filter is needed for EMI suppression. The RC Pi topology offers effective attenuation without active components. Consider the thermal performance and physical dimensions of the 3-XQFN package during board space-constrained designs.

Part Context

This part belongs to NXP's family of passive EMI/RFI filters. These components are engineered to meet stringent electromagnetic compatibility standards. The series provides various impedance and capacitance combinations to suit different frequency filtering requirements in modern electronic systems.

Replacement Considerations

Check for direct substitutes with identical RC values and package dimensions. Verify that alternative suppliers offer the same SOT883 footprint and electrical characteristics to ensure seamless integration without redesigning the PCB.
