Inrush Current Limiters (ICL) Procurement Notes

Verify the specific package dimensions and lead termination type against the official Vishay datasheet before integration. Confirm that the 22 Ohm resistance value aligns with the circuit's steady-state requirements after the initial inrush period. Ensure the 120°C thermal rating meets the ambient conditions of the final assembly environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 22 Ohm initial resistance is required for inrush limiting. Consider the 22mm diameter for board space constraints. Evaluate the 25% tolerance impact on circuit consistency. Compare against other Vishay Ametherm ICL series for voltage ratings and thermal performance suitability.
