Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix against official documentation, as standard listings typically reference SL102R505 without an 'A' suffix. Confirm that the requested variant does not alter electrical parameters or physical dimensions compared to the base model. Cross-reference manufacturer datasheets to ensure compatibility with existing design specifications before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component for applications requiring moderate inrush current limiting up to 5 A at standard mains voltages. The 10 mm diameter provides sufficient thermal mass for repeated cycling. Ensure PCB layout accommodates the 5 mm lead pitch and allows adequate clearance for heat dissipation during high-current startup events.
