Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure the correct variant is selected. Confirm that the radial leaded package style matches the target PCB layout requirements. Cross-reference the electrical parameters, specifically the 10 Ohm resistance and 8 A current rating, with the system design specifications to guarantee adequate performance under operational conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a radial leaded form factor is required for mechanical stability or automated insertion processes. Ensure the application demands an inrush current limit within the 8 A capability and can accommodate the 10 Ohm initial resistance. Evaluate the thermal environment to confirm the 200 J energy rating provides sufficient margin for the expected surge events without exceeding the device's thermal limits.
