Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific part number matches the required electrical parameters, specifically the 60-ohm resistance and 2-amp current rating. Confirm that the 15mm package size fits the intended PCB layout. Ensure compliance with any relevant safety certifications such as UL approval required for the final equipment assembly. Check datasheet revisions for any updates to thermal or electrical specifications before ordering.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the application requires limiting inrush current to protect downstream components like capacitors or transformers. The 60-ohm initial resistance and 2-amp steady-state capability define its suitability for moderate power loads. Consider the thermal dissipation requirements and the maximum energy rating of 50 Joules to ensure the device can withstand the specific surge conditions of the target circuit without failure.

Inrush Current Limiters (ICL) Part Context

This component is part of the Vishay Ametherm SL15 series of MegaSurge inrush current limiters. These devices are negative temperature coefficient (NTC) thermistors designed to reduce high initial charging currents. The series offers various resistance values and disk sizes to accommodate different power levels and physical space constraints in electronic equipment designs.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 60-ohm resistance, 2-amp current rating, and 15mm diameter. Verify that alternative parts offer comparable energy absorption capabilities and meet the same safety certification standards. Ensure the replacement maintains similar thermal characteristics to avoid overheating issues in the existing design.
