PEMI2QFN/HR,115

Overview

The PEMI2QFN/HR,115 is a second-order low-pass RC (Pi) EMI filter manufactured by Nexperia USA Inc. It features two channels with a resistance of 45 Ohms per channel and a total capacitance of 21pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for data line protection, it offers integrated ESD suppression capabilities alongside signal filtering. The device operates within a temperature range of -40°C to 85°C and complies with RoHS3 standards.

Feature Summary

• Integrates passive RC filtering with electrostatic discharge protection in a single compact package
• Provides second-order low-pass attenuation for high-frequency noise reduction on data lines
• Supports dual-channel operation for simultaneous signal conditioning and protection

Applications

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

Procurement Notes

Verify the manufacturer status carefully as this specific part number may be discontinued or subject to product change notifications. Confirm current availability through authorized distributors or alternative sources like Rochester Electronics if direct supply from Nexperia is unavailable. Ensure the ordering suffix matches the required tape and reel configuration for automated assembly processes.

Selection Notes

Select this component when space-constrained designs require combined ESD protection and EMI filtering for differential or single-ended data lines. The 45-ohm impedance aligns with standard USB and similar interface requirements. Consider the 6-pin XFDFN footprint for PCB layout compatibility. Verify that the 21pF total capacitance meets the bandwidth requirements of the target application without excessive signal degradation.

Part Context

This device belongs to the PEMIxQFN family of integrated passive filter networks. These components are designed to replace discrete R, C, and TVS diode arrangements, simplifying bill of materials and reducing assembly complexity. The family includes variants with different resistance values and channel counts to suit various interface speeds and protection levels.
