NAM-20-471

Power Line Filter Modules Overview

The NAM-20-471 is a single-phase power line filter module manufactured by Cosel USA, Inc. It belongs to the NAM series and is designed for chassis mounting with push-down terminal connections. The unit supports AC voltages up to 250 VAC and DC voltages up to 250 VDC. It handles a rated current of 20 A and features a capacitance value of 470 pF. This configuration results in a maximum leakage current of 12.5 μA. The device operates as a single-stage EMC/EMI filter.

Power Line Filter Modules Feature Summary

• Single-stage electromagnetic interference suppression
• Low leakage current design for safety compliance
• Chassis mount construction for secure installation

Power Line Filter Modules Applications

• Industrial equipment power conditioning
• Medical device power supply filtering
• Electronic instrumentation noise reduction

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the NAM-20-471 to confirm exact mechanical dimensions and terminal torque specifications. Ensure compatibility with the target chassis mounting holes and verify that the 20 A current rating meets the system requirements. Confirm RoHS compliance status through official manufacturer documentation before integration.

Power Line Filter Modules Selection Notes

Select this component when a single-phase filter with low leakage current is required for 250 VAC systems. The 20 A rating suits moderate power applications. Compare against the NBM series if higher current capacity is needed, or the NAP series for different capacitance values. Verify terminal type compatibility with existing wiring harnesses.

Power Line Filter Modules Part Context

This model is part of the NAM series from Cosel, which includes variants like NAM-16-471 and NAM-30-471. These filters share similar mounting styles and voltage ratings but differ in current handling capabilities. The series is designed for general-purpose EMI suppression in AC and DC power lines.

Power Line Filter Modules Replacement Considerations

Direct substitutes include NAM-16-471 for lower current needs or NAM-30-471 for higher current demands within the same series. Cross-series replacements like NBM-20-471 may offer similar electrical characteristics but require verification of physical footprint and terminal configuration.
