Power Line Filter Modules Procurement Notes

Verify the specific suffix designation against official Cosel documentation to ensure correct terminal type and mounting hardware compatibility. Confirm that the 3 A current rating aligns with the system's continuous load requirements. Check for updated compliance certifications relevant to the target market before finalizing procurement orders.

Power Line Filter Modules Selection Notes

Select this model when a compact, single-phase filter is required for low-current applications up to 3 A. Ensure the chassis mounting method fits the enclosure design constraints. Verify that the 250 VAC/VDC rating matches the local supply voltage and that the leakage current specifications meet safety limits for sensitive loads.

Power Line Filter Modules Part Context

This component belongs to the ESP series of power line filters from Cosel. The series offers various current ratings and capacitance values to suit different noise attenuation needs. The ESP-03-681 specifically targets low-power single-phase applications where space efficiency and standard compliance are prioritized over high-capacity filtering.

Power Line Filter Modules Replacement Considerations

Consult official Cosel substitution guides for verified equivalents. Generic replacements may not match the specific 680 pF capacitance or chassis mounting dimensions.
