1539M16

Overview

The Hammond Manufacturing 1539M16 is a fixed power inductor designed for heavy-duty applications. It features an unshielded drum core construction with wirewound technology, suitable for radial vertical cylinder mounting. The component provides an inductance of 500 µH and supports a maximum DC current of 3.7 A. Its maximum DC resistance is specified at 129 mΩ. This part belongs to the 1539 series and utilizes wire leads for termination.

Feature Summary

• Heavy-duty RF choke design for robust circuit performance
• Unshielded drum core configuration for specific electromagnetic requirements
• Radial vertical cylinder package for standard board integration

Applications

• RF filtering in electronic circuits
• Power supply noise suppression
• Signal integrity maintenance in communication systems

Procurement Notes

Verify the exact inductance tolerance and saturation current limits against your specific circuit requirements before ordering. Confirm that the radial lead spacing matches your PCB footprint. Ensure the unshielded nature of the component does not interfere with nearby sensitive traces or components in your final assembly layout.

Selection Notes

Select this model when a 500 µH inductance value is required with a 3.7 A current rating. Consider the unshielded design if magnetic field containment is not critical. Compare physical dimensions against available board space. Evaluate thermal dissipation capabilities given the 129 mΩ resistance under load conditions.

Part Context

This component is part of the Hammond Manufacturing 1539 series, which specializes in fixed inductors for industrial and commercial electronics. The series offers various inductance values tailored for different filtering needs. The 1539M16 specifically addresses applications requiring moderate inductance with high current handling capabilities.

Replacement Considerations

Check datasheets for alternative inductors with matching 500 µH inductance and similar current ratings. Verify pin compatibility and mechanical fit for direct substitution. Ensure equivalent electrical characteristics such as DC resistance and self-resonant frequency are met by potential replacements.
