Procurement Notes
Verify the component status as obsolete before procurement planning. Confirm that RoHS compliance information is unavailable for this specific part number. Ensure that the wire lead termination style matches your assembly requirements. Validate that the 3A current rating and 250VAC voltage specifications meet your system design constraints prior to ordering.
Selection Notes
Select this component when a two-stage filtering solution is required for single-phase AC lines. The 3A rating suits low-power electronic equipment. Consider the wire lead termination if through-hole or direct wiring is preferred over PCB mount options. Verify that the chassis mounting method aligns with your enclosure design. Ensure the operating frequency range covers your specific 50/60Hz application needs.
Part Context
This component belongs to the ER Series of power line filter modules from Curtis Industries. It is categorized under passive components within the filters product line. The series focuses on providing essential electromagnetic compatibility solutions for industrial and commercial electronic assemblies requiring reliable noise attenuation.
Replacement Considerations
No public confirmed substitute part numbers are available for this obsolete component. Evaluate alternative two-stage line filters from other manufacturers if sourcing is critical. Ensure any replacement meets the 3A current and 250VAC voltage ratings.
