Inrush Current Limiters (ICL) Procurement Notes

Verify the specific manufacturing status, as this part number may be discontinued or subject to obsolescence notices. Confirm that the 8 Ohm resistance and 5 Ampere current ratings align with the target circuit's peak load requirements. Ensure the thermal dissipation capabilities meet the system's ambient temperature constraints before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current handling and the magnitude of the expected inrush pulse. Evaluate the thermal time constant to ensure it matches the duty cycle of the application. Consider the physical size constraints due to the 16 mm diameter package when designing the PCB layout.

Inrush Current Limiters (ICL) Part Context

This component belongs to the category of inrush current limiters, which are critical for protecting sensitive downstream electronics from damage caused by sudden current spikes. Unlike standard resistors, these devices dynamically adjust their impedance based on temperature, offering efficient protection without significant continuous power loss once stabilized.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ICLs by matching the 8 Ohm resistance, 5 A current rating, and 16 mm form factor.
