NBH-10-681-D

Overview

The NBH-10-681-D is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It supports a rated AC voltage of 250V and a DC voltage of 250V with a continuous current rating of 10A. The device features a two-stage filtering configuration and utilizes terminal block connections for circuit integration. Designed for chassis mounting, it operates within a temperature range of -40°C to 85°C. The unit holds CURUS and VDE certifications, ensuring compliance with international safety standards for electronic equipment.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Terminal block connection style for secure wiring
• Chassis mount installation type for stable positioning

Applications

• Industrial control systems requiring EMI mitigation
• Medical equipment power input stages
• General purpose electronic devices needing EMC compliance

Procurement Notes

Verify the specific suffix 'D' against official Cosel documentation to confirm terminal orientation or pinout variations. Ensure the required current rating of 10A aligns with system design limits. Confirm that chassis mounting hardware is included or sourced separately as per mechanical drawings. Check for updated certification marks such as CURUS and VDE on the final delivered units to meet regulatory requirements.

Selection Notes

Select this component when a single-phase filter with a 10A capacity is required for 250VAC/VDC applications. The two-stage design offers superior attenuation compared to single-stage alternatives. Consider the chassis mounting requirement during enclosure design. Verify that the operating temperature range of -40°C to 85°C meets environmental conditions. Terminal block interfaces simplify integration into existing panel layouts.
