Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm lead configuration and tolerance. Ensure the selected variant matches the required thermal characteristics and physical footprint for the target PCB layout. Cross-reference the Mouser part number 995-SL18-5R006 for accurate sourcing details.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 5 Ohm initial resistance and 6 A current handling capability. Confirm that the 19 mm diameter fits within the available board space. Validate that the 115 VAC/230 VAC rating aligns with the system's operating voltage requirements.

Inrush Current Limiters (ICL) Part Context

This device belongs to the Vishay Ametherm MegaSurge SL18 series of inrush current limiters. These components are engineered to protect downstream electronics from high surge currents by providing high cold resistance that decreases as temperature rises during operation.

Inrush Current Limiters (ICL) Replacement Considerations

SL185R007A offers similar functionality with kinked leads and a 7 A rating. SL155R006 provides a smaller 15 mm diameter profile with identical electrical specifications.
