NAC-20-222

Power Line Filter Modules Overview

The NAC-20-222 is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It supports a rated current of 20 A and operates at voltages up to 250 V AC or DC. The device features a single-stage configuration with terminal block connections for input and output. It is designed for chassis mounting and functions within an operating temperature range of -40°C to +85°C. The filter provides attenuation characteristics relevant to electromagnetic interference suppression in general-purpose applications.

Power Line Filter Modules Feature Summary

• Single-phase electromagnetic interference filtering capability
• Terminal block connection interface for circuit integration
• Chassis mounting design for stable installation
• Wide operating temperature range suitability

Power Line Filter Modules Applications

• General purpose electronic equipment noise suppression
• Industrial control system power line conditioning
• Medical device power input filtering
• Information technology equipment EMI reduction

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as NAC-20-222-D exist with potentially different termination styles or certifications. Confirm that the required voltage rating of 250V AC/DC aligns with the target application's electrical specifications. Ensure chassis mounting provisions are available in the host enclosure. Check for RoHS compliance status if environmental regulations apply to the deployment region. Validate lead times with authorized distributors as availability may fluctuate.

Power Line Filter Modules Selection Notes

Select this component based on the requirement for a 20 A continuous current capacity in single-phase systems. The 250 V rating limits suitability for higher voltage industrial networks. Consider the terminal block interface if screw-type connections are preferred over PCB pins. Evaluate the -40°C to +85°C range against ambient thermal conditions. Compare physical dimensions against available chassis space before finalizing the design.

Power Line Filter Modules Part Context

This model belongs to Cosel's NAC series of power line filters, which are engineered for compact EMI suppression in various electronic assemblies. The series typically offers multiple current ratings and voltage options to accommodate diverse power distribution needs. These modules are commonly integrated into devices requiring compliance with electromagnetic compatibility standards for conducted emissions.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other single-phase 20 A filters from Cosel, such as the NAP-20-222, though pinout and mounting differences must be verified. Cross-brand replacements require matching current, voltage, and attenuation specifications. Verify that alternative components support the same terminal block interface or adaptability to existing wiring harnesses.
