IP4251CZ12-6,118

Overview

The IP4251CZ12-6,118 is a six-channel passive RC (Pi) EMI/RFI filter network manufactured by NXP USA Inc. It integrates low-pass filtering with electrostatic discharge (ESD) protection in a single surface-mount package. The component features a resistance of 100 Ohms and a total capacitance of 10 pF per channel. It operates within a temperature range of -40°C to 85°C and utilizes a 12-XFDFN exposed pad package for compact board integration.

Feature Summary

• Integrates second-order low-pass RC filtering with ESD protection capabilities
• Provides six independent signal channels for multi-line interface protection
• Utilizes a compact surface-mount package design for space-constrained applications

Applications

• Local Area Network (LAN) interfaces
• Wide Area Network (WAN) connections
• High-speed digital data line protection

Procurement Notes

Verify the specific ordering suffix and manufacturer designation carefully, as NXP Semiconductors and Nexperia are related entities. Confirm current availability status, as some listings indicate obsolete or limited supply conditions. Ensure the package type matches the required footprint for your PCB layout before finalizing procurement decisions.

Selection Notes

Select this component when simultaneous ESD protection and high-frequency noise attenuation are required on multiple signal lines. The integrated RC topology simplifies bill of materials compared to discrete solutions. Verify that the 100 Ohm resistance and 10 pF capacitance values align with the impedance and bandwidth requirements of the target interface signals.
