Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm that it denotes the correct UL certification status or packaging variant. Ensure the selected part matches the required 50 Ohm resistance and 1.1 A current rating for the target application circuit design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 50 Ohm cold resistance is required to manage inrush currents up to 1.1 A. Consider the 10 mm diameter for spatial constraints on the PCB layout. Verify thermal dissipation requirements and ambient operating conditions to ensure the thermistor remains within its safe operating area during continuous operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of inrush current limiters from Vishay Ametherm. The series offers various resistance values and physical sizes to accommodate different power levels. The SL1050001-A specifically targets applications requiring moderate surge suppression with established safety certifications.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other Vishay Ametherm SL10 series variants if different resistance or current ratings are needed. Ensure any substitute maintains the same radial lead configuration and UL approval status for direct compatibility.
