Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact electrical tolerances and lead configurations. Ensure the selected variant matches the required thermal characteristics for the target application environment. Cross-reference the part number with official Vishay documentation to validate compliance with relevant safety standards before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the circuit's peak inrush current requirements and the steady-state operating current limit. Evaluate the resistance value to ensure effective surge suppression without excessive voltage drop during normal operation. Consider the physical dimensions and lead spacing to fit the designated PCB layout constraints.

Inrush Current Limiters (ICL) Part Context

This device belongs to the SL08 series, which comprises compact NTC inrush current limiters designed for space-constrained applications. The series offers various resistance values and current ratings to suit different power levels while maintaining a consistent 8 mm form factor for standardized mounting solutions.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the official Vishay Ametherm substitution guide for verified equivalent parts. Direct replacements must match the 40 Ohm resistance, 2 A current rating, and 8 mm package dimensions.
