PEMI2QFN/CK,115

Overview

The PEMI2QFN/CK,115 is a second-order low-pass RC Pi-filter network manufactured by Nexperia USA Inc. under the NXP brand. It features two channels with an integrated ESD protection structure. The component utilizes a 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Electrical specifications include a channel resistance of 100 ohms and a total capacitance of 21pF. It provides attenuation of 25dB at frequencies between 800MHz and 3GHz. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates passive RC filtering with electrostatic discharge protection in a single compact package
• Provides high-frequency signal attenuation for data line noise suppression
• Supports bidirectional signal transmission through dual-channel architecture

Applications

• Local Area Network (LAN) interface protection
• Personal Computer System (PCS) data lines
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix designation during procurement, as variations such as CK, HR, or HM indicate distinct internal configurations within the PEMIxQFN family. Confirm that the selected variant matches the required electrical parameters and pinout compatibility for the target design. Cross-reference official datasheets to ensure the component meets current RoHS3 compliance standards before finalizing orders.

Selection Notes

Select this component when space-constrained designs require combined ESD protection and RF interference filtering. The 6-pin XFDFN package suits applications needing minimal footprint while maintaining performance up to 3GHz. Ensure the 100-ohm impedance aligns with the system's differential trace requirements. Consider the operating temperature range for environmental suitability.

Part Context

This part belongs to the PEMIxQFN series, which integrates passive filter networks with ESD diodes. The series offers various channel counts and package types to address different interface protection needs. The CK suffix denotes a specific configuration within this family, differentiated from other variants like HR or HM by internal circuit topology or parameter tolerances defined in the manufacturer's documentation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pin assignments and electrical characteristics against alternative components from the same manufacturer or third-party suppliers.
