Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESP-03-471-D exist with different mounting styles like DIN rail. Confirm that the required certification marks (UL, CSA, etc.) match your regional regulatory requirements. Ensure the chassis mounting holes align with your enclosure design before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a 3 A single-phase filter is required for chassis installation. Compare against the ESP-03-471-D if DIN rail mounting is preferred instead. Verify that the 470 pF capacitance meets your specific leakage current constraints, as other models in the series offer different values.

Power Line Filter Modules Part Context

This part belongs to the ESP series of power line filters from Cosel. The series includes various current ratings and capacitance options. The ESP-03-471 specifically denotes the 3 Ampere rating and 470 picofarad capacitance configuration within this product family.

Power Line Filter Modules Replacement Considerations

The ESP-03-471-D is a related variant offering DIN rail mounting instead of chassis mounting. Direct substitution requires verifying mechanical fit and terminal type compatibility.
