PEMI2QFN/RT,115

Overview

The PEMI2QFN/RT,115 is a second-order low-pass RC(Pi) EMI filter manufactured by Nexperia USA Inc. It features two channels with a resistance of 100 Ohms per channel and a total capacitance of 23 pF. The device provides an attenuation value of 25 dB in the frequency range of 800 MHz to 3 GHz. It is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. The component operates within a temperature range of -40°C to 85°C and is RoHS3 compliant.

Feature Summary

• Integrates dual-channel RC Pi topology for effective common-mode noise suppression
• Provides high attenuation performance across the 800 MHz to 3 GHz spectrum
• Designed for compact surface-mount applications with minimal footprint

Applications

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

Procurement Notes

Verify the specific suffix 'RT' against official Nexperia documentation to confirm the exact capacitance value, as variations exist within the family. Confirm the component status, as similar parts in this series may be obsolete. Ensure the 6-XFDFN package dimensions match the design constraints. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status before procurement.

Selection Notes

Select this component when space-constrained designs require dual-channel EMI filtering for high-speed data lines. The 100-ohm resistance and 23-pF capacitance values are optimized for impedance matching in standard digital interfaces. Consider the 6-XFDFN package size relative to board real estate requirements. Evaluate the thermal operating range to ensure compatibility with the intended environmental conditions of the final assembly.

Part Context

This component belongs to the PEMIxQFN family of EMI filters from Nexperia. These devices are engineered to suppress electromagnetic interference in high-speed digital circuits. The QFN packaging allows for efficient heat dissipation and reliable soldering on printed circuit boards. This specific variant utilizes the RT suffix to denote particular electrical characteristics within the broader product line.

Replacement Considerations

PEMI2QFN/RR,115 is a documented substitute within the same family, featuring a total capacitance of 21 pF instead of 23 pF. Verify that the slight capacitance difference does not impact signal integrity in the specific application.
