155H

Overview

The Hammond Manufacturing 155H is a leaded DC reactor and filter choke designed for open channel mounting. It features an inductance of 5 H with a tolerance of 15%. The component has a maximum DC resistance of 270 Ohm and a current rating of 50 mA. It utilizes 5-inch wire leads for connection.

Feature Summary

• Fixed inductance design for filtering applications
• Open channel mounting configuration
• Leaded construction with extended wire terminals

Applications

• DC circuit filtering
• Choke applications in low current systems
• Power supply noise reduction

Procurement Notes

Verify the specific inductance value and current rating against the target circuit requirements before procurement. Confirm that the 270 Ohm DC resistance is acceptable for the application's voltage drop constraints. Ensure the 5-inch lead length accommodates the physical layout of the assembly.

Selection Notes

Select this component when a fixed 5 H inductance is required for DC filtering. The 50 mA current rating limits its use to low-power circuits. The open channel design requires appropriate mechanical support during installation. Compare the 270 Ohm resistance against other available options if lower impedance is necessary.

Part Context

This part belongs to the Hammond 155 series of power inductors. It is categorized as a leaded component, distinct from surface-mount alternatives. The series offers various inductance values, but the 155H specifically provides 5 H at 50 mA.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model.
