154EA

Overview

The Hammond Manufacturing 154EA is a leaded DC reactor and filter choke designed for open channel mounting. It features an inductance of 15 H with a maximum DC current rating of 20 mA. The component exhibits a maximum DC resistance of 966 ohms and maintains a tolerance of ±15% for both inductance and resistance values. Inductance measurements are conducted at the rated DC current to ensure accuracy under operating conditions. This surface mount power inductor belongs to the 153-159 series, providing reliable performance for filtering applications requiring specific impedance characteristics.

Feature Summary

• Economical open bracket channel mount design for straightforward installation
• Inductance measured at rated DC current for operational accuracy
• Consistent 15% tolerance applied to both inductance and resistance specifications

Applications

• DC reactor implementation in power supply circuits
• Filter choke usage for noise suppression in electronic systems
• Open channel mount integration in industrial control panels

Procurement Notes

Verify the exact part number 154EA against manufacturer documentation to confirm compatibility with your circuit requirements. Ensure that the 20 mA current rating and 15 H inductance align with your design parameters. Check for any specific handling instructions related to the open channel mount structure. Confirm availability through authorized distributors as lead times may vary. Always refer to the official datasheet for precise electrical characteristics and mechanical dimensions before finalizing procurement decisions.

Selection Notes

Select this component when a high inductance value of 15 H is required within a low current environment up to 20 mA. The open channel mount style suits applications where space constraints allow for external mounting rather than direct PCB soldering. Consider the 966 ohm DC resistance impact on voltage drop in your circuit design. The 15% tolerance provides standard precision suitable for general filtering tasks. Evaluate if the physical dimensions fit within the intended enclosure or chassis layout.

Part Context

The 154EA is part of Hammond Manufacturing's 153-159 series of surface mount power inductors. This series focuses on providing economical solutions for DC filtering and reactor applications. The components are characterized by their leaded construction and open channel mounting capability, distinguishing them from fully enclosed SMD variants. Hammond Manufacturing specializes in electrical enclosures and components, ensuring these inductors meet commercialized standards for reliability in industrial and commercial electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should verify compatibility based on identical electrical parameters: 15 H inductance, 20 mA current rating, and similar mounting style. Cross-referencing with other Hammond series parts may require careful evaluation of mechanical fit and electrical performance differences.
