NBH-30-101

Overview

The NBH-30-101 is a single-phase EMC/EMI power line filter from the Cosel NBH series, rated for 30 A current and 250 VAC/DC voltage. It features a two-stage configuration with terminal block connections for chassis mounting. The unit utilizes common mode noise filtering technology to suppress electromagnetic interference within the 10 kHz to 10 MHz frequency range. Key electrical specifications include a maximum leakage current of 12.5 uA and a capacitance of 100 pF. The component weighs approximately 320 g and is supplied in bulk packaging.

Feature Summary

• Two-stage common mode noise filtering architecture
• Terminal block connection interface
• Chassis mount installation style

Applications

• General purpose power conditioning
• EMC/EMI suppression in AC/DC systems
• Industrial equipment power input stages

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as NBH-30-101-D exist with potentially different mechanical or electrical characteristics. Confirm lead times prior to purchase, as production cycles may extend up to 26 weeks depending on manufacturer availability. Ensure compatibility with existing chassis mounting hardware and terminal block requirements during integration planning.

Selection Notes

Select this model for applications requiring 30 A continuous current handling with strict leakage current limits below 12.5 uA. The two-stage design offers enhanced attenuation compared to single-stage alternatives. Verify that the 250 VAC/DC rating aligns with the system's nominal voltage levels. Consider the physical dimensions and weight constraints associated with chassis-mounted industrial filters.

Part Context

This component belongs to the Cosel NBH series of power line filters, which are engineered for robust electromagnetic interference suppression in demanding environments. The series provides various current ratings and capacitance options to suit different power distribution needs while maintaining low leakage currents and high reliability standards for industrial and commercial power supplies.

Replacement Considerations

The NBH-30-101-D is a documented variant within the same product family. Verify if the '-D' suffix indicates a specific mechanical modification or certification difference before substituting. Cross-reference datasheets to ensure identical current, voltage, and leakage current specifications match the original design requirements.
