IP4051CX11/LF,135

Overview

The IP4051CX11/LF,135 is an integrated RC(PI) filter component manufactured by NXP USA Inc. Designed for surface-mount applications, this device integrates specific passive components to manage signal integrity and electromagnetic interference. The unit features a 47 Ohm resistance and 25 picofarad capacitance configuration within a compact 11-WFBGA WLCSP package. It is RoHS compliant and intended for high-density electronic assemblies requiring efficient EMI suppression in data line filtering scenarios.

Feature Summary

• Integrates RC(PI) filter topology for compact EMI suppression
• Designed for surface-mount technology (SMD) assembly
• RoHS compliant construction for environmental safety

Applications

• Data line filtering in consumer electronics
• EMI suppression in mobile devices
• Signal integrity management in high-speed interfaces

Procurement Notes

Verify the complete part number including the suffix LF,135 to ensure correct packaging and compliance status. Confirm that the 11-WFBGA WLCSP package matches your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability of the component batch.

Selection Notes

Select this component when a specific 47 Ohm/25PF PI-filter response is required for EMI reduction. The choice depends on the need for a small form factor via the WLCSP package. Consider the integration level compared to discrete components for space-constrained designs. Verify compatibility with the target signal frequency range and voltage levels before implementation.

Part Context

This component belongs to the IP405x series of integrated filters from NXP. These parts are engineered to replace multiple discrete passive components, reducing board space and assembly complexity. The series typically targets applications requiring robust EMI filtering in portable and compact electronic devices where size and performance are critical constraints.

Replacement Considerations

Check for direct substitutes such as the IP4052CX20/LF,135 or IP4054CX15/LF,135 if parameter adjustments are needed. Verify pinout and package compatibility before swapping. Ensure the alternative maintains the required filtering characteristics for the specific application circuit.
