Procurement Notes
This component is classified as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or alternative sourcing channels. Ensure compatibility with existing designs before procurement due to discontinuation status.
Selection Notes
Select this part for applications requiring specific 25-ohm resistance and 50-picofarad capacitance values in an SMD form factor. Verify that the 20-SOIC package dimensions fit the PCB layout constraints. Consider the obsolete status when planning long-term production runs.
Part Context
The 4420P series represents Bourns' line of passive EMI filters. These components integrate resistors and capacitors into single packages to simplify circuit design. The 601 suffix typically denotes the specific electrical characteristics within this family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official replacement guides or contact the manufacturer directly for qualified alternatives.
