Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct lead time and packaging configuration. Confirm that the kinked lead variant matches your assembly requirements. Cross-reference the RoHS status directly with the manufacturer's latest compliance declarations prior to final procurement decisions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when board space is limited and a low-profile inrush limiter is required. Ensure the 1 A current rating and 120 Ohm resistance align with the target circuit's peak load and steady-state operating conditions. Validate compatibility with the intended PCB layout regarding the 5 mm lead spacing and kinked lead geometry.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 series from Vishay Ametherm, which specializes in miniaturized inrush current limiters.
