Power Line Filter Modules Procurement Notes

Verify the specific suffix '-D' indicates the DIN rail mounting variant and screwless terminals, as generic part numbers may differ. Confirm RoHS3 compliance status for environmental regulations. Ensure the 3 A current rating and 250 VAC/VDC voltage limits match the target circuit requirements. Check for updated certification marks such as ENEC if operating in European markets.

Power Line Filter Modules Selection Notes

Select this component when single-phase noise filtration is required for low-current applications up to 3 A. The screwless terminal feature offers faster assembly compared to screw-type alternatives. Verify that the 75.5 uA leakage current is acceptable for sensitive medical or safety-critical equipment. Ensure physical space accommodates DIN rail mounting constraints.
