- Power line filtering applications requiring compact form factors
Procurement Notes
Verify the part status carefully as sources indicate this specific revision may be obsolete. Confirm the manufacturer designation, noting potential transitions between NXP and Nexperia branding. Ensure the ordering suffix matches the required specifications exactly. Request official documentation to validate current availability and compliance status before procurement decisions.
Selection Notes
Select this component when a multi-channel solution is required to save board space. The 100 Ohm resistance and 30pF capacitance values define the cutoff frequency characteristics. Consider the XFDFN package dimensions for layout constraints. Verify that the integrated nature meets the system's isolation requirements compared to discrete components.
Part Context
This component belongs to the family of integrated EMI filters designed for signal line protection. It serves as a consolidated alternative to discrete LC or RC networks, reducing component count and assembly complexity. The product is categorized under passive filtering solutions for maintaining signal quality in noisy environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer databases for cross-reference information regarding equivalent performance specifications.
