NAP-20-472

Power Line Filter Modules Overview

The NAP-20-472 is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It is rated for 20 A current and operates at voltages up to 250 VAC and 250 VDC. The unit features a single-stage filtering design intended for high-voltage pulse applications requiring high attenuation. It utilizes terminal block connections for circuit integration.

Power Line Filter Modules Feature Summary

• Single-stage noise filtration architecture
• Terminal block connection interface
• High-attenuation performance for high-voltage pulses

Power Line Filter Modules Applications

• General-purpose power line filtering
• Equipment requiring high-voltage pulse suppression
• Industrial control systems

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as NAP-20-472-D exist within the product family. Confirm RoHS compliance status with the supplier prior to purchase. Ensure the selected variant matches the required terminal type and voltage rating for the target application.

Power Line Filter Modules Selection Notes

Select this component for single-phase circuits requiring 20 A capacity. The single-stage design suits applications where space or cost constraints preclude multi-stage filters. Verify that the 250 VAC/DAC rating aligns with the system's maximum operating voltage and that terminal block mounting is compatible with the enclosure design.

Power Line Filter Modules Part Context

This part belongs to the Cosel NAP series of single-phase noise filters. The series is engineered for general-purpose EMI/EMC suppression in AC and DC power lines. The model number indicates the current rating and specific internal component configuration within the standardized form factor.

Power Line Filter Modules Replacement Considerations

The NAP-20-472-D is a documented variant within the same product line. Cross-referencing with other Cosel models like the NAH-20-472 requires verification of stage count and terminal type differences.
