SL1810005B

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1810005B is a radial lead inrush current limiter designed for PCB mounting. It features a nominal resistance of 10 Ohms with a tolerance of ±20%. The device supports a steady-state current rating of 5 A and operates at voltage ratings of 115 VAC or 230 VAC. The component has a cylindrical body diameter of 19.00 mm (0.748 inches) with a lead pitch of 7.8 mm.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation.

Inrush Current Limiters (ICL) Applications

• Protection against inrush currents in power supply circuits
• Surge current limiting in AC/DC converters
• Electronic equipment input stage protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'B' corresponds to the required lead configuration, as standard variants may differ. Confirm RoHS compliance status through official documentation before integration. Ensure thermal management requirements align with the component's dissipation characteristics during continuous operation.

Inrush Current Limiters (ICL) Selection Notes

Select this part when a 10 Ohm initial resistance and 5 A steady-state current capacity are required. The 19 mm diameter provides sufficient thermal mass for moderate surge applications. Verify that the 7.8 mm lead pitch matches the target PCB footprint design constraints.

Inrush Current Limiters (ICL) Part Context

This component belongs to the SL18 series of inrush current limiters from Vishay Ametherm. The series offers various resistance and current ratings within a standardized 18-19 mm form factor, facilitating consistent mechanical design across different power handling requirements.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include the SL1810005, which shares identical electrical parameters but may differ in lead style. Cross-reference with other Vishay SL18 series parts if current or resistance values require adjustment while maintaining the same package dimensions.
