1540M02

Overview

The Hammond Manufacturing 1540M02 is a heavy-duty RF choke belonging to the 1540 series. It features an unshielded toroidal core design with radial vertical open mounting. The component provides an inductance of 25 µH and supports a maximum DC current of 3.25 A. Its direct current resistance is specified at a maximum of 14 mΩ. The unit utilizes a leaded construction suitable for through-hole integration.

Feature Summary

Unshielded toroidal core configuration
Radial vertical open leaded mounting style
Heavy-duty industrial RF choke design

Applications

RF filtering in industrial automation systems
DC link choke applications
Signal integrity management in electronic circuits

Procurement Notes

Verify the specific inductance value of 25 µH and the 3.25 A current rating against project requirements. Confirm that the unshielded toroidal form factor aligns with spatial constraints. Ensure the radial vertical package matches the PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when an unshielded toroidal choke is required for RF suppression. The 14 mΩ maximum resistance indicates low power loss characteristics. Consider the physical dimensions and lead spacing to ensure compatibility with existing assembly processes and board real estate.

Part Context
