• Designed for low leakage current operation
• Supports both AC and DC voltage environments

Power Line Filter Modules Applications

• Industrial equipment power conditioning
• Commercial machinery EMC compliance
• DIN rail mounted control panels

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the NAM-04-221-D to confirm exact leakage current ratings (25 uA vs 50 uA) as documentation may vary. Ensure compatibility with the target DIN rail type and verify that the 4A current rating meets the circuit requirements. Confirm RoHS3 compliance status if required by local regulations before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a compact, single-stage EMI filter is needed for 4A circuits. The 220 pF capacitance offers a balance between noise suppression and minimal leakage current. Consider the DIN rail mounting requirement and screw terminal accessibility during PCB or panel layout planning. Ensure the operating temperature range aligns with the installation environment.

Power Line Filter Modules Part Context

This part belongs to the NAM series of power line filters from Cosel USA, Inc. The series includes various current ratings and capacitance values. The NAM-04-221-D specifically denotes the 4A variant with 220 pF capacitance. It is distinct from the NBH series which typically handles higher currents like 6A.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes in the NAM series with identical 4A ratings and 220 pF capacitance. Verify pinout and mounting dimensions match existing enclosures. Consult manufacturer cross-reference lists for updated part numbers if discontinuations occur.
