Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'BT' against official Vishay documentation to confirm lead time and packaging details. Ensure the selected variant matches the required voltage ratings and physical mounting constraints for the target PCB layout. Cross-reference the Mouser part number 995-SL0812101-BT for availability status.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 120 Ohm initial resistance is required to limit startup surges in circuits operating up to 1 Ampere. The 8 mm form factor suits space-constrained designs. Consider the thermal characteristics and energy absorption capabilities to ensure compatibility with the system's peak power requirements during initialization.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 miniAMP series of NTC thermistors manufactured by Vishay Ametherm. These components are engineered for compact electronic assemblies where effective inrush current limiting is critical for protecting downstream circuitry from high initial charging currents.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official substitution lists for equivalent SL08 variants or other Vishay Ametherm ICLs with matching resistance and current ratings. Verify that any substitute maintains the same voltage ratings and physical footprint for direct replacement.
