NBH-10-322

Overview

The NBH-10-322 is a single-phase power line filter manufactured by Cosel USA, Inc. It features a common mode noise filtering design with a capacitance of 3.2 nF. The component supports AC voltages up to 250 VAC and DC voltages up to 250 VDC, handling a rated current of 10 A. Leakage current is specified at a maximum of 0.75 mA. Operating frequency ranges from 10 kHz to 10 MHz. It utilizes chassis mount installation with screw termination.

Feature Summary

• Common mode noise filtration for electromagnetic interference suppression
• Dual voltage rating capability for AC and DC power lines
• Chassis mount construction with screw terminal connections

Applications

• Industrial equipment power supply input stages
• Medical device power conditioning
• Communication system power filtering

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm leakage current limits and capacitance values. Ensure the chassis mounting configuration matches the enclosure design requirements. Confirm that the screw termination type aligns with available wiring hardware. Cross-reference the part number suffix to ensure no functional variations exist compared to standard configurations.

Selection Notes

Select this model when a 10 A current capacity is required for single-phase applications. The 250 VAC/DC rating suits standard low-voltage industrial systems. Consider the chassis mount style if panel integration is preferred over PCB mounting. Verify that the 3.2 nF capacitance provides adequate attenuation for the target frequency range without exceeding leakage current safety standards for connected loads.

Part Context

This component belongs to the NB series of power line filters from Cosel. The series includes variants with different current ratings such as the NBH-16-322 and NBH-30-322. These filters are designed for EMI/EMC compliance in power distribution networks. The NBH-10-322 specifically addresses the 10 A segment of this product family.

Replacement Considerations

The NBH-10-322-D is listed as a related variant. Verify if the DIN rail mount option in the -D suffix meets mechanical requirements. Other models in the NBH series may offer different current capacities but require re-evaluation of electrical specifications.
