IP4251CZ16-8,118

Overview

The IP4251CZ16-8,118 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It functions as a second-order low-pass network designed to suppress electromagnetic and radio frequency interference in electronic systems. The component features eight channels with a resistance of 100 Ohms and a total capacitance of 10 picofarads per channel. It is housed in a 16-pin XFDFN package with an exposed pad, providing surface-mount integration for compact circuit designs.

Feature Summary

• Provides effective suppression of electromagnetic interference (EMI) and radio frequency interference (RFI)
• Integrates an RC Pi-network topology for second-order low-pass filtering
• Features eight independent signal channels within a single compact package

Applications

• Data line protection in high-speed digital interfaces
• Signal integrity enhancement in consumer electronics
• Electromagnetic compatibility improvement in communication modules

Procurement Notes

Verify the exact suffix and tape-and-reel specifications against the official NXP datasheet before ordering. Confirm that the 16-XFDFN package dimensions match your PCB footprint requirements. Ensure compliance with RoHS directives if required for your specific manufacturing process. Check current availability status as this part may be subject to end-of-life or supply constraints.

Selection Notes

Select this component when eight-channel filtering is required for signals requiring 100 Ohm impedance matching and minimal parasitic capacitance. The XFDFN package is suitable for applications demanding small board space and thermal dissipation through the exposed pad. Compare performance against LC filters if higher attenuation at lower frequencies is needed, noting the trade-offs in size and cost.

Part Context

This device belongs to the IP4251 series of EMI filters from NXP Semiconductors. It is specifically engineered for protecting multiple data lines simultaneously. The series offers various configurations with different resistance and capacitance values to suit diverse signal speeds and impedance requirements across industrial and consumer applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components such as the IP4253CZ16-8,118 only if the increased resistance and capacitance values align with the specific circuit design requirements.
