154B

Overview

The Hammond Manufacturing 154B is a leaded power inductor designed as a DC reactor and filter choke. It features an open channel mount configuration with unshielded construction. The component provides an inductance of 3 mH with a tolerance of 15%. It supports a maximum DC current of 1.5 A and exhibits a maximum DC resistance of 140 mohms. The unit utilizes wire leads for termination and is intended for chassis mounting applications within the 153-159 series.

Feature Summary

• Functions as a DC reactor and filter choke for circuit stabilization
• Features unshielded open channel construction for thermal management
• Utilizes wire leads for standard chassis mounting integration

Applications

• DC power supply filtering
• Choke applications in electronic circuits
• Industrial control system power regulation

Procurement Notes

Verify the specific inductance value against project requirements, as datasheets may list variations between 1.5 mH and 3 mH for similar part numbers. Confirm that the 1.5 A current rating aligns with the operational load. Ensure the open channel mounting style fits the available chassis space. Cross-reference the manufacturer number to avoid confusion with shielded variants or different series components.

Selection Notes

Select this component when an unshielded inductor is required for high-current DC filtering applications. The open channel design facilitates heat dissipation compared to enclosed cores. Verify that the wire lead termination method matches the PCB or terminal block layout. Consider the physical dimensions and chassis mounting constraints before finalizing the design to ensure proper fitment within the enclosure.

Part Context

This component belongs to the Hammond Manufacturing 153-159 series of power inductors. These parts are engineered for robust performance in industrial environments. The series offers various inductance values and current ratings to suit different power processing needs. The 154B specifically addresses applications requiring moderate inductance with significant current handling capabilities.

Replacement Considerations

Direct substitutes include other Hammond Manufacturing unshielded DC reactors from the same series with matching electrical parameters. Verify that any replacement maintains the 1.5 A current rating and compatible inductance value. Ensure the physical footprint and mounting style remain consistent with the existing design constraints.
