Overview
The IP4047CX6/LF,135 is a dual-channel integrated passive filter network manufactured by Nexperia USA Inc. It functions as an EMI/RFI filter utilizing RC (Pi) topology. The component integrates a resistance value of 0.9 Ohms and a capacitance value of 290 pF per channel. Designed for surface-mount applications, it is housed in a compact 6-WFBGA or WLCSP package with a maximum height of 0.65 mm. This device provides signal conditioning and electromagnetic interference suppression for consumer circuits.
Feature Summary
- Integrates dual-channel low-pass filtering within a single compact footprint
- Combines resistive and capacitive elements to suppress EMI and RFI noise
- Provides electrostatic discharge (ESD) protection capabilities
- Utilizes Pi-network RC topology for effective signal integrity maintenance
Applications
- Consumer electronic circuit signal conditioning
- EMI and RFI noise suppression in data lines
- Electrostatic discharge protection for sensitive interfaces
Procurement Notes
Verify the specific suffix LF,135 against official Nexperia documentation to confirm lead-free compliance and reel packaging specifications. Ensure the selected distributor sources directly from authorized channels to guarantee authenticity. Cross-reference the 6-WFBGA package dimensions with your PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select this component when space-constrained designs require integrated passive filtering without external discrete components. The dual-channel configuration supports independent signal paths within a minimal area. Consider the 0.9 Ohm series resistance impact on signal attenuation and the 290 pF shunt capacitance effect on bandwidth when evaluating compatibility with high-speed interface requirements.
Part Context
This part belongs to Nexperia's portfolio of integrated passive devices designed for modern electronics. It addresses the industry trend toward miniaturization by consolidating multiple passive functions into a single semiconductor package. The product line targets applications demanding robust noise immunity and ESD resilience in compact form factors.
Replacement Considerations
Consult official Nexperia substitution guides for verified alternatives. Generic equivalents may not match the precise 0.9 Ohm/290 pF characteristics or the specific WLCSP footprint. Verify pinout compatibility and thermal performance before considering any cross-references.
