Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the EAM-20-471 to confirm exact leakage current specifications and thermal derating curves. Ensure the terminal block type matches the PCB or wire termination requirements of the target design. Cross-reference with the official Cosel catalog to confirm availability of the -D suffix variant if lead-free compliance is required.

Power Line Filter Modules Selection Notes

Select this component when a 20 A continuous current rating is required for single-phase power lines. Consider the voltage rating of 250 VAC/VDC against the system's maximum operating voltage. Evaluate the physical dimensions and terminal block orientation to ensure compatibility with the enclosure layout and wiring harness configuration.
