NAP-04-471

Power Line Filter Modules Overview

The NAP-04-471 is a single-phase power line filter manufactured by Cosel USA, Inc. It features a chassis mount configuration with screw termination style. The component is rated for 250 VAC and 250 VDC operation with a current rating of 4 A. Key electrical specifications include a maximum leakage current of 0.25 mA and a capacitance value of 1 nF. It belongs to the NA series and is designed for common mode noise filtering applications.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtration for AC and DC power lines
• Designed for secure chassis mounting using screw terminals
• Operates within a wide temperature range from -40°C to 85°C

Power Line Filter Modules Applications

• General purpose EMC/EMI suppression in industrial equipment
• Power conditioning for sensitive electronic devices
• Chassis-mounted noise filtering in control panels

Power Line Filter Modules Procurement Notes

Verify the specific part number suffix when ordering, as variants such as NAP-04-471-D exist with different mounting styles like DIN rail. Confirm that the chassis mount requirement matches your enclosure design. Ensure the 4 A current rating and 250 VAC/VDC voltage limits are sufficient for your circuit. Check for RoHS compliance status if required by your manufacturing standards. Review the official datasheet for precise mechanical dimensions and terminal torque specifications before integration.

Power Line Filter Modules Selection Notes

Select this model when chassis mounting is preferred over DIN rail installation. The 1 nF capacitance offers a balance between leakage current reduction and filtering effectiveness. Consider the NAP-04-471-D variant if DIN rail compatibility is required instead. Ensure the operating environment stays within the specified -40°C to 85°C temperature range. Verify that the screw terminal type aligns with your wiring infrastructure.

Power Line Filter Modules Part Context

This component is part of the Cosel NA series of power line filters. The series includes various models differentiated by current ratings, capacitance values, and mounting configurations. The NAP-04-471 specifically targets applications requiring robust chassis-mounted filtering solutions with moderate current handling capabilities.

Power Line Filter Modules Replacement Considerations

The NAP-04-471-D serves as a related variant within the same series but utilizes DIN rail mounting instead of chassis mounting. Direct substitution requires verifying mechanical fitment and terminal accessibility. Other models in the NA series may offer different current or voltage ratings.
