NBM-10-101

Overview

The NBM-10-101 is a single-phase EMC/EMI line filter manufactured by Cosel USA, Inc. It supports AC voltages up to 250 VAC and DC voltages up to 250 VDC with a rated current of 10 A. The device features a two-stage filtering configuration designed for chassis mounting using screw terminal blocks. Key electrical specifications include a maximum leakage current of 12.5 uA and a capacitance value of 100 pF. It operates within a temperature range of -40°C to 85°C and holds certifications from UL, CSA, DIN, VDE, and ENEC.

Feature Summary

• Two-stage filtering architecture for effective noise suppression
• Low leakage current design suitable for sensitive equipment
• Chassis mount installation with screw terminal connections

Applications

• Industrial power supply units
• Medical electronic devices
• General purpose AC/DC power systems

Procurement Notes

Verify the specific datasheet version for the NBM-10-101 to confirm exact mechanical dimensions and terminal torque specifications before integration. Ensure that the mounting surface can withstand the operating temperature range of -40°C to 85°C. Cross-reference certification marks such as UL and VDE against regional regulatory requirements for the final assembly. Confirm that the 10 A current rating aligns with the system's peak load demands to prevent thermal overload during continuous operation.

Selection Notes

Select this component when a single-phase filter with a 10 A capacity is required for chassis-mounted applications. The low leakage current specification makes it appropriate for medical or safety-critical environments where ground fault limits are strict. Compare the 100 pF capacitance value against other models in the NB series if higher attenuation or different current ratings are needed. Ensure the screw terminal interface matches the existing wiring harness or busbar configuration in the design.

Part Context

This part belongs to the NB series of power line filters from Cosel USA, Inc., which offers various current ratings and configurations. The NBM-10-101 specifically denotes the 10 A variant within this family. Similar parts in the series include the NBM-06-101 for lower current applications and the NBM-20-101 for higher current needs. All share common mounting styles and certification profiles but differ in electrical ratings.

Replacement Considerations

Direct substitutes within the same series include the NBM-10-000 or NBM-10-471, depending on specific terminal or certification variations. Verify that any replacement maintains the 10 A rating and 250 VAC/VDC voltage limits. Ensure mechanical compatibility with the existing chassis cutout and terminal spacing.
