NBH-06-681-D

Overview

The NBH-06-681-D is a single-phase power line filter module manufactured by Cosel USA, Inc. It supports a rated current of 6A and operates with a voltage rating of 250VAC/VDC. The unit features a two-stage filtering configuration designed for noise suppression in electrical circuits. It utilizes a DIN rail mounting style for secure installation on standard rails. The device complies with RoHS3 standards and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• DIN rail mounting configuration for standardized integration
• Dual voltage rating capability for AC and DC applications

Applications

• General purpose industrial equipment protection
• Power supply input filtering for sensitive electronics
• DIN rail mounted control panel installations

Procurement Notes

Verify the specific suffix 'D' indicates the DIN rail variant when sourcing replacements. Confirm that the 6A rating aligns with the circuit's continuous load requirements. Ensure the 250VAC/VDC rating exceeds the maximum system voltage. Check for RoHS3 compliance if environmental regulations apply to the final assembly. Validate physical dimensions against available DIN rail space constraints.

Selection Notes

Select this component where a compact, two-stage solution is required for general-purpose noise reduction. The DIN rail format simplifies retrofitting into existing enclosures. Consider the 6A current limit when sizing for higher-power loads. The wide temperature range supports operation in varied environmental conditions without derating adjustments.

Part Context

This model belongs to the NBH series of power line filters from Cosel USA, Inc. The series offers various current ratings and mounting options. The NBH-06-681-D specifically denotes the 6A capacity with DIN rail compatibility. It serves as a passive EMI/RFI suppression component in power distribution networks.

Replacement Considerations

Direct substitutes include other NBH series models with identical 6A ratings and DIN rail footprints. Verify that alternative parts maintain the same two-stage topology and 250VAC/VDC rating. Ensure physical mounting hole patterns match the existing enclosure design.
