SL0820002

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL0820002 is a negative temperature coefficient (NTC) inrush current limiter designed for PCB mounting. It features radial leads and a cylindrical body with an 8 mm diameter. The component has a nominal resistance of 20 Ohms with a tolerance of ±20%. It supports a steady-state current rating of 2 A and operates at voltage ratings of 115 VAC or 230 VAC. The unit weighs approximately 0.6 grams.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up to protect downstream components
• Utilizes NTC thermistor technology to automatically reset after cooling down
• Features a compact radial leaded package suitable for standard PCB layouts

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics AC/DC adapters
• Industrial control circuit protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure correct resistance and current ratings. Confirm that the radial lead spacing matches your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the operating environment does not exceed the specified thermal limits.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-cost, compact solution is needed for limiting inrush current in low-power applications. The 20 Ohm resistance value is suitable for smaller loads requiring up to 2 A steady-state current. Consider the physical size constraints of the 8 mm diameter package. Evaluate the thermal dissipation capabilities relative to the expected ambient temperatures in the final assembly.

Inrush Current Limiters (ICL) Part Context

This device belongs to the miniAMP SL08 series of inrush current limiters from Vishay Ametherm. The series offers various resistance values and current ratings within a standardized small form factor. These components are widely used in general-purpose electronic equipment where space is limited and cost efficiency is prioritized over high-power handling capabilities.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 20 Ohm resistance, 2 A current rating, and 8 mm diameter. Verify that alternative NTC thermistors have compatible lead spacing and thermal characteristics. Cross-reference with other manufacturers offering similar miniAMP-style packages to ensure mechanical fit and electrical performance equivalence.
