1539M18

Overview

The Hammond Manufacturing 1539M18 is a fixed wirewound inductor from the 1539 series, designed for heavy-duty RF choke applications. It features an unshielded drum core construction with radial vertical cylinder termination. The component provides an inductance of 2.5 mH with a tolerance of 15%. It supports a maximum DC current of 1.6 A and has a maximum DC resistance of 690 milliohms.

Feature Summary

• Heavy-duty RF choke design suitable for demanding circuit environments
• Unshielded drum core configuration for specific electromagnetic compatibility requirements
• Radial vertical cylinder package for standard through-hole mounting

Applications

• Distributed Antenna Systems (DAS)
• RF filtering circuits
• DC reactor applications

Procurement Notes

Verify the exact inductance value and current rating against the official Hammond Manufacturing datasheet before integration. Confirm that the unshielded nature of the component aligns with the system's electromagnetic interference constraints. Ensure the radial vertical package dimensions fit the target PCB layout without mechanical interference.

Selection Notes

Select this component when a 2.5 mH inductance value is required for RF or power filtering duties. The 1.6 A current rating dictates suitability for moderate power levels. Consider the unshielded design if magnetic coupling with adjacent components must be minimized or managed differently than shielded alternatives.

Part Context
