Power Line Filter Modules Procurement Notes

Verify the specific part number suffix against official Cosel documentation to ensure correct terminal type and mounting style. Confirm that the required current rating of 20 A aligns with your system design. Check RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Power Line Filter Modules Selection Notes

Select this model when chassis mounting is preferred over DIN rail configurations. Ensure the application requires a 20 A current rating rather than higher capacity variants like the 30 A models. Verify that the 220 pF capacitance value meets the specific EMC requirements of the target circuit without causing excessive leakage current issues.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAH series of power line filters. It shares similar electrical characteristics with other models in the family but differs in mounting style and current handling capabilities. The NAH-20-221 specifically targets applications requiring robust chassis-mounted solutions for single-phase power line noise reduction.

Power Line Filter Modules Replacement Considerations

NAH-20-221-D serves as a variant with different mounting or terminal specifications. NAP-30-221 offers higher current capacity but uses different mounting styles. Verify mechanical dimensions and terminal compatibility before substituting with these related models.
