Power Line Filter Modules Procurement Notes

Verify the specific terminal configuration against design requirements, as datasheets may list both screw and screwless variants within the ESP-03 series. Confirm that the 3 A current rating and 250 VAC/VDC voltage limits align with the target circuit parameters. Ensure chassis mounting provisions are available in the enclosure design to accommodate the physical dimensions and weight of the filter module.

Power Line Filter Modules Selection Notes

Select this model when a compact single-phase filter is required for general-purpose applications. The screwless terminal option offers faster assembly compared to traditional screw types. Consider the 50 uA leakage current specification for safety compliance in sensitive environments. Verify that the 170 g weight does not exceed mechanical constraints of the mounting structure.

Power Line Filter Modules Part Context

This component is part of the ES series from Cosel USA, Inc., which specializes in power line filter modules. The series includes various current ratings and terminal configurations to suit different power supply needs. The ESP-03-472 specifically addresses low-current applications requiring reliable EMI attenuation without complex installation procedures.

Power Line Filter Modules Replacement Considerations

The EAP-03-472 is a related variant within the same manufacturer's lineup, offering similar performance characteristics but potentially differing in terminal style or specific certification details. Cross-referencing datasheets is necessary to confirm interchangeability regarding mounting and connection methods.
