IP4048CX5/LF,135

Overview

The IP4048CX5/LF,135 is a two-channel RC Pi EMI filter manufactured by Nexperia USA Inc. Designed for surface-mount applications, this component integrates resistive and capacitive elements to attenuate high-frequency noise while maintaining signal integrity. It utilizes a 5-UFBGA WLCSP package, offering a compact footprint suitable for space-constrained designs. The device operates as an effective low-pass filter network, providing essential electromagnetic interference suppression for sensitive data lines in portable electronics.

Feature Summary

• Integrates RC Pi topology for dual-channel noise filtering
• Provides high-frequency attenuation while passing desired signals
• Utilizes wafer-level chip scale packaging for minimal board area

Applications

• Smartphone display interface protection
• Portable device data line filtering
• High-speed serial communication noise suppression

Procurement Notes

Verify the specific suffix LF,135 against the manufacturer's current datasheet to confirm lead-free compliance and reel specifications. Confirm availability status directly with authorized distributors, as production cycles may vary. Ensure the selected package matches the PCB footprint requirements precisely before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring integrated EMI suppression for differential or single-ended high-speed signals. The small WLCSP form factor makes it ideal for mobile devices where board real estate is limited. Ensure the operating voltage and capacitance values align with the target signal frequency characteristics to maintain optimal filtering performance without signal degradation.

Part Context

This part belongs to Nexperia’s portfolio of EMI filter circuits, specifically targeting consumer electronics and mobile communications. It complements other signal conditioning components by addressing electromagnetic compatibility challenges at the source.
