PEMI2QFN/HM,115

Overview

The PEMI2QFN/HM,115 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features two channels with a resistance of 45 Ohms per channel and a total capacitance of 16 pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for signal line protection, it provides attenuation of 25dB from 800MHz to 3GHz while offering electrostatic discharge (ESD) protection.

Feature Summary

• Integrates RC Pi-filter topology for effective high-frequency noise suppression
• Provides dual-channel ESD protection for sensitive data lines
• Utilizes ultra-small 6-XFDFN package for space-constrained designs

Applications

• Local Area Network (LAN) interfaces
• Personal Computer Systems (PCS)
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix HM against the official Nexperia/NXP datasheet to confirm the 45 Ohm/16pF configuration. Confirm RoHS3 compliance status as required by your assembly specifications. Check current product lifecycle status, as this part may be obsolete or subject to change without notice. Ensure the 6-XFDFN footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring combined ESD protection and EMI filtering for high-speed digital signals. The 45 Ohm resistance value offers a balance between signal integrity and noise attenuation. Consider the 16pF total capacitance impact on signal rise times for your specific data rate requirements. The small form factor makes it suitable for portable devices and dense motherboard layouts where space is limited.

Part Context

This device belongs to the PEMIxQFN family of EMI filters designed for protecting I/O ports. It integrates passive filtering elements with ESD diodes in a single surface-mount package. The series is engineered to meet stringent electromagnetic compatibility standards while providing robust protection against transient voltage events on communication lines.

Replacement Considerations

Check the official Nexperia replacement guide for direct pin-compatible alternatives. Verify that any substitute maintains the same 45 Ohm resistance and 16pF capacitance values. Ensure the replacement component supports the same XFDFN-6 package dimensions and thermal characteristics.
