Overview
The IP4254CZ12-6,118 is a six-channel RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration designed for signal line protection. The component integrates resistors with a resistance of 100 Ohms and capacitors totaling 30 pF per channel. It is housed in a compact 12-XFDFN package with an exposed pad, suitable for surface-mount assembly in space-constrained electronic designs requiring effective noise suppression.
Feature Summary
- Six independent channels for multi-line signal filtering
- RC Pi-network topology for enhanced attenuation
- Second-order low-pass frequency response
- Compact surface-mount packaging with thermal pad
Applications
- LAN interface protection
- WAN signal line filtering
- High-speed data bus noise suppression
- Embedded system I/O protection
Procurement Notes
Verify the manufacturer designation as NXP USA Inc. or Nexperia USA Inc., as both entities are associated with this part number in distribution channels. Confirm the suffix 118 corresponds to the specific reel quantity and tape-and-reel packaging format required for automated assembly processes. Ensure the 12-XFDFN package footprint matches the PCB design guidelines provided in the official datasheet.
Selection Notes
Select this component when designing circuits that require simultaneous filtering of multiple differential or single-ended signals within a limited board area. The 100 Ohm resistor value and 30 pF capacitance provide a balanced impedance match for common digital interfaces. Consider the thermal performance of the exposed pad if high current handling or heat dissipation is a concern in the final application environment.
Part Context
This device belongs to the family of integrated EMI/RFI filters utilizing RC networks. Unlike discrete LC components, this monolithic solution offers consistent electrical characteristics across all six channels. The XFDFN package provides superior electromagnetic shielding compared to standard leaded packages, making it suitable for sensitive analog and digital mixed-signal applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin compatibility and electrical parameters before considering alternative manufacturers. Consult official distributor databases for cross-reference lists based on specific impedance and capacitance requirements.
