NAM-20-221-D

Power Line Filter Modules Overview

The NAM-20-221-D is a single-phase power line filter manufactured by Cosel USA, Inc. It features a rated voltage of 250 VAC and 250 VDC with a current rating of 20 A. The component utilizes screw termination and is designed for DIN rail mounting. It operates within a frequency range of 10 kHz to 10 MHz and has a maximum leakage current of 25 uA. The capacitance value is 220 pF.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtering for AC and DC power lines
• Designed for low leakage current applications
• Supports DIN rail installation for secure mounting

Power Line Filter Modules Applications

• Industrial control systems requiring EMI suppression
• Medical equipment with strict leakage current limits
• Precision instrumentation power supplies

Power Line Filter Modules Procurement Notes

Verify the specific suffix 'D' indicates DIN rail mounting style as distinct from chassis mount variants. Confirm the 220 pF capacitance value matches system requirements. Ensure the 20 A current rating aligns with load specifications. Check RoHS compliance status if required by project standards.

Power Line Filter Modules Selection Notes

Select this model when DIN rail mounting is preferred over chassis mounting for the NAM series. Compare against NAM-20-221 if chassis mounting is acceptable. Verify that the 20 A rating meets peak load demands. Consider the 25 uA leakage limit for sensitive patient-connected or measurement devices.

Power Line Filter Modules Part Context

This component belongs to the NAM series of power line filters from Cosel. The series includes variants with different current ratings and mounting styles. The NAM-20-221-D specifically denotes the 20 A version with DIN rail compatibility. Other variants include NAM-30-221 for higher current applications.

Power Line Filter Modules Replacement Considerations

NAM-20-221 is a chassis mount alternative within the same series. NAM-20-221-DXE may be an equivalent variant depending on packaging. Verify mechanical dimensions and terminal types before substitution.
