Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version from Vishay or authorized distributors to confirm UL approval status and detailed thermal characteristics. Ensure the selected component matches the required 2.5-ohm resistance and 15-ampere current rating for the target application. Cross-reference physical dimensions against PCB layout constraints before finalizing procurement decisions.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 2.5-ohm initial resistance is required to limit peak charging currents. The 15-ampere rating suits moderate power applications. Verify that the 265 VAC voltage rating aligns with the system's operating voltage. Consider the radial package style for through-hole assembly processes.

Inrush Current Limiters (ICL) Part Context

The SG160 belongs to the Surge-Gard series of inrush current limiters produced by Vishay Ametherm. This series employs negative temperature coefficient thermistors to protect sensitive electronics from high startup currents. The SG160 specifically targets applications requiring robust surge suppression with standardized radial packaging.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official Vishay documentation for verified substitute part numbers within the SG series. Ensure any replacement maintains equivalent electrical parameters, including resistance, current rating, and voltage limits.
