Embedded systems requiring high-current RF chokes

Procurement Notes

Verify the specific suffix against official Hammond Manufacturing documentation to confirm electrical characteristics and physical dimensions. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the datasheet for any recent revisions that may affect performance specifications.

Selection Notes

Select this component when a high-current RF choke with 400 µH inductance is required for PCB-mounted applications. Consider the unshielded nature of the toroidal design regarding electromagnetic interference sensitivity in the target environment. Evaluate the 2.25 A current rating against peak load requirements to ensure reliable operation without saturation.

Part Context

This part belongs to the Hammond Manufacturing 1540 series, which specializes in heavy-duty hash chokes. These components are engineered for demanding RF applications where high current handling and stable inductance are critical. The series provides reliable performance in industrial and communication equipment environments.

Replacement Considerations
