• Offers compact radial package suitable for space-constrained printed circuit board layouts

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the SL0310001 to confirm exact dimensional tolerances and thermal derating curves. Ensure that the application environment does not exceed the specified maximum surface temperature of 150°C. Confirm compatibility with standard PCB assembly processes for radial components.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10-ohm initial resistance and 1-ampere continuous current capacity are required. Consider the 3 mm body size for spatial constraints. Evaluate the total capacitance of the downstream circuit against the manufacturer's maximum capacitance ratings to ensure proper operation without excessive heating.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL03 series of inrush current limiters manufactured by Vishay Ametherm. These components are thermistors designed specifically to protect electronic equipment from damage caused by high surge currents during initial energization. The series offers various resistance and current ratings to suit different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts within the SL03 series with matching electrical parameters, such as the SL0320001 for higher resistance applications. Cross-brand replacements require careful verification of resistance values, current ratings, and physical dimensions to ensure functional equivalence.
