NAP-10-221-D

Power Line Filter Modules Overview

The Cosel NAP-10-221-D is a single-phase, single-stage power line filter designed for AC and DC applications. It features a rated voltage of 250 VAC and 250 VDC with a current rating of 10 A. The unit utilizes a common mode noise filtering configuration with a capacitance of 220 pF. Leakage current is specified at a maximum of 25 uA for AC and 50 uA for DC. Designed for DIN rail mounting with screw termination, it operates within a frequency range of 10 kHz to 10 MHz.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtration for single-phase circuits
• Supports both AC and DC power line environments
• Enables secure DIN rail installation via screw terminals

Power Line Filter Modules Applications

• Industrial control panel EMC suppression
• Power supply input stage filtering
• Electrical equipment noise reduction

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the NAP-10-221-D to confirm compliance certifications such as UL, CSA, or VDE, as these vary by region and manufacturing batch. Ensure the operating environment temperature falls within the standard industrial range. Confirm that the 10 A continuous current rating aligns with the system's peak load requirements to prevent thermal overload during sustained operation.

Power Line Filter Modules Selection Notes

Select this component when a low-leakage current specification is critical for safety compliance in sensitive AC/DC systems. The 220 pF capacitance offers a balance between noise attenuation and minimal impact on power quality. Choose this model over higher-capacitance variants if strict leakage limits are required, noting that higher capacitance options in the series may increase leakage current significantly.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAP series of power line filters, which are engineered for single-phase applications. The series provides various current ratings and capacitance values to suit different EMI/EMC requirements. The NAP-10-221-D specifically addresses mid-range current needs with low leakage characteristics, fitting into the broader portfolio of chassis and DIN-rail mounted filtering solutions.

Power Line Filter Modules Replacement Considerations

The NAP-10-102-D serves as a functional substitute within the same series, offering identical 10 A current and 250 VAC/VDC ratings but with a higher capacitance of 1 nF. Verify that the increased capacitance does not exceed allowable leakage current limits for the target application before substitution.
