• Radial kinked lead termination style for secure PCB installation
• Capable of suppressing high inrush current surges in power systems

Inrush Current Limiters (ICL) Applications

• Mounting within power control boxes using DIN blocks
• Integration into switch mode power supplies (SMPS)
• General inrush current limiting in electronic circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the exact specifications against the official datasheet before procurement, as this part number represents a custom configuration. Confirm that the 5 Ohm resistance, 9 A current rating, and 16 mm diameter meet the design requirements. Ensure the radial kinked lead style is compatible with the target PCB layout. Cross-reference the UL approval status if safety certification is mandatory for the end application.

Inrush Current Limiters (ICL) Selection Notes

Select this component when standard catalog values do not match the required electrical parameters. The 5 Ohm resistance and 9 A rating define its thermal and current handling limits. Consider the 16 mm diameter for spatial constraints on the PCB. The kinked lead style aids in mechanical stability during assembly. Verify compatibility with 115 VAC and 230 VAC operating voltages.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Vishay Ametherm SL15 series of NTC thermistor inrush current limiters. The series offers various diameters and resistance values to suit different power levels. The SL155R00903A is a customized variant, differing from standard off-the-shelf parts by its specific combination of resistance, current rating, and physical dimensions tailored for particular industrial or commercial power applications.

Inrush Current Limiters (ICL) Replacement Considerations

No public confirmed substitute part numbers are available for this custom configuration. Standard SL15 series components may serve as alternatives only if their electrical ratings and physical dimensions align with the original design requirements.
