1540M17

Overview

The Hammond Manufacturing 1540M17 is a fixed inductor belonging to the 1540 series, designed for heavy-duty RF and hash choke applications. It features an unshielded toroidal core construction with radial vertical open leads. The component provides an inductance of 500 µH and supports a maximum DC current of 2.75 A. It exhibits a maximum DC resistance of 150 mΩ. This inductor is suitable for EMI/RFI filtering and energy storage in switching power supplies.

Feature Summary

• Unshielded toroidal core design for robust performance
• Radial vertical open lead configuration for through-hole mounting
• Heavy-duty construction optimized for high-current applications

Applications

• EMI and RFI filtering circuits
• Energy storage inductors for switching power supplies
• High-current RF choke applications

Procurement Notes

Verify the specific electrical parameters against the official Hammond Manufacturing datasheet before integration. Confirm that the 500 µH inductance and 2.75 A current rating align with the circuit requirements. Ensure the unshielded toroidal form factor fits within the mechanical constraints of the target assembly.

Selection Notes

Select this component when unshielded toroidal inductors are required for high-current environments. The 1540 series offers a balance of inductance and current handling capacity. Consider the radial lead style for standard PCB layouts. Evaluate thermal management needs as the unit operates without shielding.
