Inrush Current Limiters (ICL) Procurement Notes

Verify the specific package dimensions and lead time requirements directly with authorized distributors or the manufacturer before ordering. Ensure that the 1.7A current rating aligns with the maximum steady-state operational current of the target application circuit to prevent thermal failure. Confirm compatibility with the mounting method required by the design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when designing circuits requiring passive inrush current limiting for low-power applications up to 1.7A. Consider the 16 Ohm initial resistance value to ensure adequate surge suppression while minimizing steady-state power loss. Evaluate the thermal environment to ensure the device can dissipate heat effectively during repeated power cycles without exceeding its thermal limits.
