SL1010003

Inrush Current Limiters (ICL) Overview

The SL1010003 is a radial leaded negative temperature coefficient (NTC) thermistor from the Vishay Ametherm SL10 series, designed as an inrush current limiter. It features a nominal resistance of 10 ohms with a tolerance of ±20% and a continuous current rating of 3 amperes. The component has a cylindrical body diameter of 10 mm. It is UL approved for safety compliance.

Inrush Current Limiters (ICL) Feature Summary

• Radial leaded construction for through-hole PCB mounting
• Negative temperature coefficient characteristic for automatic resistance reduction after startup
• UL recognized safety certification

Inrush Current Limiters (ICL) Applications

• Switching power supply input stages
• Electronic ballast circuits
• Transformer protection applications

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix and manufacturer designation when sourcing, as distributors may list this under Vishay or Ametherm branding. Confirm that the required 10 mm package size fits the target PCB layout. Ensure the 3 A continuous current rating meets the operational requirements of the specific circuit design to prevent thermal overload during steady-state operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 ohm initial resistance is required to limit peak charging currents in capacitive loads. The 3 A rating suits moderate power applications. Consider the 10 mm diameter for mechanical clearance. Compare against other SL series variants if different current ratings or resistance values are needed for higher or lower power systems.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of inrush current limiters. It shares the same physical form factor and NTC technology as other parts in the family but differs in electrical parameters such as resistance and current handling capacity. It serves as a protective component in AC/DC conversion stages.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts within the SL10 series that match the 10 ohm resistance and 3 A current rating. Cross-brand replacements require matching the 10 mm diameter, radial lead configuration, and UL approval status to ensure identical mechanical and safety integration.
