Procurement Notes
Verify the specific part number against official Cosel documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with chassis mounting requirements and screw termination specifications. Confirm lead times and availability directly with authorized distributors or the manufacturer, as supply chain conditions may vary. Validate RoHS compliance status through the latest datasheet before integration.
Selection Notes
Select this component when a 20 A current rating and 100 pF capacitance are required for common mode noise attenuation. Ensure the application environment supports chassis mounting and screw terminations. Verify that the operating frequency range of 10 kHz to 10 MHz aligns with the noise spectrum to be filtered. Confirm that the leakage current limit of 12.5 uA meets safety standards for the intended AC or DC system.
Part Context
This component is part of the NB series from Cosel USA, Inc., categorized under power line filters. It serves as a passive electromagnetic interference suppression device. The NB series typically includes various configurations for different current and voltage ratings. This specific model focuses on high-current applications requiring low leakage characteristics.
Replacement Considerations
The NBH-20-101-D is listed as a related variant by the manufacturer. Verify if DIN rail mounting options are acceptable alternatives to chassis mounting. Cross-reference electrical parameters such as current rating, voltage limits, and capacitance values with potential substitutes to ensure functional equivalence.
