IP4252CZ8-4,118

Overview

The IP4252CZ8-4,118 is an integrated EMI/RFI filter from NXP USA Inc., designed for surface-mount applications. It features a passive RC (PI) network configuration with four channels. Key electrical parameters include a resistance of 40 Ohms and a capacitance of 12 pF per channel. The device provides 40 dB of attenuation and incorporates Electrostatic Discharge (ESD) protection capabilities. It is housed in a compact SMD package suitable for high-density PCB layouts.

Feature Summary

• Integrates a four-channel passive RC PI-filter network for effective signal line conditioning
• Provides built-in electrostatic discharge (ESD) protection to safeguard connected components
• Delivers significant electromagnetic interference attenuation within a compact footprint

Applications

• High-speed data interface lines requiring EMI suppression
• USB and other peripheral connections needing ESD protection
• Consumer electronics with limited board space for filtering components

Procurement Notes

Verify the exact suffix and tape-and-reel specifications against the official NXP datasheet before ordering. Confirm that the 40 Ohm resistance and 12 pF capacitance values align with your circuit design requirements. Ensure compatibility with your assembly process regarding the specific surface-mount package type and moisture sensitivity level defined in the manufacturing documentation.

Selection Notes

Select this component when a multi-channel solution is required to simultaneously address EMI filtering and ESD protection on parallel signal lines. The integrated nature reduces component count compared to discrete RC networks. Evaluate the trade-off between the fixed 40 Ohm impedance and your system's signal integrity needs. This part is suitable for applications where space constraints prevent the use of larger discrete filters.

Part Context

This device belongs to NXP's family of integrated passive filter networks. These components are engineered to replace multiple discrete resistors and capacitors, simplifying the bill of materials. The integration ensures consistent performance across all channels while maintaining a low profile ideal for modern portable and compact electronic devices.

Replacement Considerations

Consult the official NXP datasheet for confirmed cross-reference part numbers. Verify that any substitute maintains the same 4-channel architecture, 40 Ohm resistance, and 12 pF capacitance values to ensure functional equivalence.
