Procurement Notes

Verify current availability status as the product may be obsolete or discontinued. Confirm RoHS3 compliance and lead-free specifications against latest manufacturer documentation. Ensure the specific suffix matches design requirements. Check for active substitute part numbers if this item is no longer in production. Validate package dimensions and thermal characteristics for PCB layout compatibility before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring integrated EMI filtering for multiple data lines within space-constrained environments. The RC Pi-filter structure offers superior attenuation compared to single-stage filters. Consider the operating temperature range and package size relative to the target application's thermal and physical constraints. Verify that the internal resistance and capacitance values align with the impedance matching requirements of the connected data bus.
