Inrush Current Limiters (ICL) Procurement Notes

Verify the specific dual-element configuration and 20-ohm resistance value against the official Vishay datasheet before integration. Confirm that the 15 A current rating and 68 mm physical footprint align with the target PCB layout and thermal management requirements. Ensure compatibility with the specified radial lead spacing for assembly processes.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a dual-chip NTC design is required to manage inrush currents up to 15 A. The 20 Ohm initial resistance offers a specific balance between peak current suppression and steady-state power dissipation compared to single-element alternatives. Consider the larger 68 mm diameter for adequate heat dissipation in high-power applications.
