153L

Overview

The Hammond Manufacturing 153L is a leaded power inductor designed as a DC reactor and filter choke. It features an open channel mount style for chassis installation. The component provides an inductance of 0.9 H with a tolerance of 15%. It supports a maximum DC current of 75 mA and has a maximum DC resistance of 125 ohms. The unit is unshielded and utilizes wire leads for termination.

Feature Summary

• Functions as a DC reactor and filter choke for circuit stabilization
• Designed for open channel mounting on chassis surfaces
• Constructed with wire leads for direct electrical connection

Applications

• DC filtering applications requiring low current handling
• Chassis-mounted electronic equipment assembly
• Power supply input or output smoothing circuits

Procurement Notes

Verify the specific datasheet version to confirm exact physical dimensions and thermal ratings before integration. Ensure the target circuit operates within the 75 mA DC current limit to prevent saturation or overheating. Confirm that the 125 ohm DC resistance aligns with system voltage drop requirements. Cross-reference the open channel mounting hole pattern with the mechanical design of the host chassis to ensure proper fitment during assembly.

Selection Notes

Select this component when a high-inductance, low-current filter is required for chassis mounting. The unshielded design may require consideration for electromagnetic interference in sensitive layouts. Compare the 0.9 H value against alternative models like the 159ZA if higher current capacity is needed. Evaluate the physical space constraints against the standard open channel footprint to ensure compatibility with existing panel designs.

Part Context

This part belongs to the Hammond Manufacturing line of power inductors and chokes. It serves as a passive component for managing current ripple and stabilizing DC lines. The 153L model is distinct from shielded variants and higher-current series, targeting specific low-power filtering niches within industrial and commercial electronics assemblies.

Replacement Considerations

The 159ZA is a related model offering 300 mH inductance and 1 A current capacity. Verify if the increased current rating or different inductance value suits the application. Ensure mechanical mounting compatibility remains consistent between the original and substitute parts.
