IP4252CZ16-8,118

Overview

The IP4252CZ16-8,118 is an eight-channel RC low-pass filter array designed for EMI/RFI suppression. It utilizes a pi-network topology with integrated resistors and capacitors to attenuate high-frequency noise on I/O ports. Key electrical parameters include a resistance of 40 Ohms per channel and a total capacitance of 12 pF. The device offers 30 kV IEC contact ESD protection and provides approximately 30 dB of filtering performance. It is housed in a compact 16-XFDFN exposed pad package suitable for space-constrained portable applications.

Feature Summary

• Eight-channel RC low-pass filter array for multi-line signal integrity
• Integrated 30 kV IEC contact ESD protection capability
• Compact leadless XFDFN package design for space optimization

Applications

• Portable electronic devices requiring EMI suppression
• High-speed data line protection interfaces
• Consumer electronics input/output port filtering

Procurement Notes

Verify component status as the IP4252CZ16-8,118 is listed as obsolete by NXP USA Inc. Confirm availability through authorized distributors or secondary markets. Ensure compliance with RoHS3 specifications if required for your manufacturing process. Check for potential tariff implications when shipping to the United States. Validate that the 16-XFDFN package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and high-level ESD protection for multiple lines. The 40 Ohm resistance and 12 pF capacitance values are optimized for specific impedance matching and cutoff frequency requirements. Consider the XFDFN package size constraints during layout planning. This part is suitable for applications where board space is limited but robust signal integrity and electrostatic discharge resilience are critical design priorities.

Part Context

This component belongs to NXP's family of highly integrated EMI/RFI filters. These devices combine passive filtering elements with ESD protection structures to simplify circuit design. The IP4252 series specifically targets portable electronics, offering a solution that reduces component count and board area compared to discrete filter and protection networks. The technology focuses on maintaining signal quality while suppressing unwanted electromagnetic interference.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the IP4252CZ16-8,118 is marked obsolete, alternative sourcing may require evaluating similar 8-channel RC filters from other manufacturers. Verify pin compatibility and electrical specifications carefully when considering cross-references.
