• Electronic test and measurement instruments

Power Line Filter Modules Procurement Notes

Verify the specific suffix (e.g., -D) against the datasheet to confirm terminal configuration and mounting hardware compatibility. Ensure the operating voltage and current ratings match the system requirements. Confirm that the chassis mount style aligns with the enclosure design. Check for required certification marks relevant to the target market.

Power Line Filter Modules Selection Notes

Select this component when a 3 A rating is sufficient for the load. Consider the chassis mount requirement versus PCB or DIN rail options if space constraints differ. Verify that the leakage current specifications meet safety isolation requirements for the application. Compare insertion loss characteristics if specific attenuation levels are critical.

Power Line Filter Modules Part Context

This part belongs to the ESC series of power line filters from Cosel. These modules are designed for general-purpose EMI suppression in low-current applications. The series offers various current ratings to suit different power distribution needs while maintaining compact form factors suitable for panel integration.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other Cosel models such as the NAH-30-472 for higher current requirements or the ESC-10-472 for increased amperage. Cross-brand replacements require matching voltage, current, and mounting specifications.
