1540M11

Overview

The Hammond Manufacturing 1540M11 is a heavy-duty RF choke and unshielded toroidal inductor from the 1540 series. It features a radial vertical open lead configuration with an inductance of 50 µH and a maximum DC resistance of 12 mΩ. The component supports a high current rating of 9.5 A, suitable for demanding power applications.

Feature Summary

Heavy-duty construction designed for robust performance
Unshielded toroidal core geometry
Radial vertical open lead termination style

Applications

EMI and RFI filtering circuits
Energy storage inductors for switching power supplies
High current signal processing

Procurement Notes

Verify the specific current rating requirements against the datasheet, as sources indicate variations between 6A and 9.5A. Confirm that the unshielded design aligns with your electromagnetic interference constraints. Ensure the radial vertical lead format fits your PCB layout before ordering.

Selection Notes

Select this component when high current handling and energy storage are primary requirements. The unshielded nature requires careful placement to avoid coupling with sensitive traces. Compare the 12 mΩ resistance against efficiency targets for your specific power supply topology.

Part Context

This part belongs to the Hammond 1540 series of RF chokes. It serves as a passive electronic component for managing high-frequency noise and storing energy in magnetic fields within industrial and commercial power electronics systems.
