Procurement Notes
Verify component status as this part is marked as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing design specifications before procurement attempts, as supply chain continuity cannot be guaranteed for end-of-life components.
Selection Notes
Select this component for applications requiring integrated EMI filtering and ESD protection in a small footprint. The 3-channel configuration suits multi-line data interfaces. Consider the 33-ohm resistance and 20-pF capacitance values for signal integrity requirements. Verify thermal performance within the specified -40°C to 85°C operating range for the target environment.
Part Context
This component belongs to the IPAD™ series from STMicroelectronics, designed for electromagnetic interference suppression. It serves as a passive filter solution for protecting sensitive electronic circuits from radio frequency interference while providing electrostatic discharge protection in portable and mobile devices.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, alternative solutions must be evaluated based on functional equivalence, including channel count, resistance/capacitance values, package dimensions, and ESD protection ratings.
