Overview
The NBH-16-471 is a single-phase power line filter module manufactured by Cosel USA, Inc. It features a two-stage common mode noise filtering configuration designed for AC and DC applications. The component supports a voltage rating of 250 VAC and 250 VDC with a current capacity of 16 A. It includes a maximum leakage current specification of 50 uA or 100 uA depending on the variant. The unit utilizes chassis mounting and terminal block connections.
Feature Summary
- Two-stage common mode noise filtering architecture
- Terminal block connection interface
- Chassis mount construction
Applications
- Industrial equipment EMC suppression
- Power supply input filtering
- Electronic device EMI reduction
Procurement Notes
Verify the exact suffix designation when ordering, as variants such as NBH-16-471-D exist with different mounting styles like DIN rail. Confirm the specific leakage current requirement (50 uA vs 100 uA) against the datasheet to ensure compliance with safety standards. Check lead times as production cycles may vary significantly from standard availability.
Selection Notes
Select this model for applications requiring robust two-stage attenuation in a compact chassis-mount form factor. Ensure the operating environment temperature range aligns with the specified -40°C to 85°C limits. Verify that the 16 A current rating meets the peak load requirements of the protected circuit without exceeding thermal boundaries.
Part Context
This component belongs to the NBH series of power line filters from Cosel USA, Inc. The series offers various current ratings and configurations for single-phase applications. The NBH-16-471 specifically addresses high-current needs with a focus on common mode interference suppression in industrial and commercial power systems.
Replacement Considerations
The NBH-16-471-D is a documented variant within the same series offering DIN rail mounting instead of chassis mounting. When substituting, verify that the mechanical footprint and terminal orientation are compatible with the existing enclosure design.
