Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for precise B-value constants and R-T curves, as these are critical for circuit simulation. Confirm that the 7.5 A current rating aligns with peak load requirements. Ensure the 29 mm diameter fits the mechanical constraints of the target assembly. Check RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this part when high current handling capability is required alongside compact radial packaging. The 12 Ohm baseline resistance offers a balance between steady-state loss and surge suppression effectiveness. Consider the 6.5 W power dissipation limit under worst-case ambient conditions. The wide temperature range ensures reliability in harsh environments where standard components might fail.

Inrush Current Limiters (ICL) Part Context
