NAM-04-471

Power Line Filter Modules Overview

The Cosel NAM-04-471 is a single-phase power line filter rated for 250 VAC and 250 VDC with a 4 A current capacity. It features low leakage current, typically 50 uA or 100 uA maximum, and utilizes a 470 pF capacitor configuration. Designed for chassis mounting with screw termination, this unit operates within a temperature range of -40°C to +85°C. The filter provides single-stage attenuation for electromagnetic interference suppression in general-purpose applications.

Power Line Filter Modules Procurement Notes

Verify the specific suffix (e.g., -D) against the datasheet to confirm mounting style and terminal type. Confirm voltage ratings match the system requirements. Check RoHS compliance status if required by project specifications. Ensure physical dimensions fit the chassis enclosure. Validate operating temperature range against environmental conditions.

Power Line Filter Modules Selection Notes

Select based on current rating of 4 A and voltage compatibility of 250 VAC/DC. Consider chassis mounting constraints and available space. Evaluate leakage current limits for safety regulations. Compare single-stage performance needs against potential multi-stage requirements. Verify terminal type matches existing wiring infrastructure.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAM series of power line filters. The series offers various current ratings and mounting options. The NAM-04-471 specifically targets lower current applications requiring compact chassis-mounted solutions. It complements higher current models like the NAM-06-471-D.

Power Line Filter Modules Replacement Considerations

Direct substitutes may include other Cosel NAM series units with similar ratings. Verify pinout and mounting hole patterns before substitution. Cross-reference leakage current and capacitance values to ensure equivalent performance.
