Procurement Notes
Verify current availability status as the part may be discontinued or subject to specific ordering requirements. Confirm exact packaging specifications and lead times directly with authorized distributors or the manufacturer. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.
Selection Notes
Select this component when multiple data lines require combined ESD protection and EMI filtering in a single footprint. The hybrid LC/RC structure offers flexibility for different impedance matching needs across various channels. Consider the 20-WFBGA/WLCSP package size constraints and operating temperature range relative to the target application environment.
Part Context
This component belongs to onsemi's portfolio of EMI/RFI filters intended for consumer electronics. It addresses the increasing need for robust signal integrity and protection in compact mobile devices. The design supports the miniaturization trends in modern hardware while maintaining effective noise reduction standards for sensitive data interfaces.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence if considering cross-references from other manufacturers.
