NAP-04-331-D

Power Line Filter Modules Overview

The Cosel USA, Inc. NAP-04-331-D is a power line filter module designed for AC 1-250V and DC 250V applications with a rated current of 4A. It features a maximum leakage current of 0.13mA or 0.25mA depending on the configuration. The unit utilizes a DIN rail mounting style and employs terminal block termination. Operating temperatures range from -40°C to +85°C.

Power Line Filter Modules Feature Summary

• Common mode noise filtering capability
• DIN rail mounting compatibility
• Terminal block termination style

Power Line Filter Modules Applications

• Industrial control systems
• Power supply input stages
• Electromagnetic interference suppression in low current circuits

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the exact leakage current specification (0.13mA vs 0.25mA) as distributor listings may vary. Confirm that the terminal block type matches your wiring infrastructure. Ensure the operating temperature range meets your environmental requirements before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a compact, DIN-rail mountable filter is required for single-phase lines up to 4A. Compare against chassis-mount variants if space constraints differ. Verify voltage ratings align with both AC and DC system potentials to ensure safe operation within the 250V limit.

Power Line Filter Modules Part Context

This part belongs to the Cosel NAP series of power line filters. The series offers various current ratings and capacitance values. The 'D' suffix typically indicates DIN rail mounting, distinguishing it from chassis-mount options within the same electrical family.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes within the NAP series with identical current and voltage ratings but different mounting styles if DIN rail space is unavailable. Verify pinout and terminal block compatibility before swapping manufacturers.
