SL2220006

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL2220006 is a BigAMP inrush current limiter (ICL) featuring a negative temperature coefficient (NTC). It has a nominal resistance of 20 ohms with a tolerance of 25%. The device supports a steady-state current of 6 A and withstands continuous currents up to 36 A. It handles an input energy capacity of 260 joules and operates at voltage ratings of 115 VAC or 230 VAC. The component utilizes a radial leaded package with a 22 mm diameter.

Inrush Current Limiters (ICL) Feature Summary

• Engineered to absorb high surge currents during initial power-up to protect downstream circuitry
• Features rapid resistance drop from high initial value to negligible levels under steady-state conditions
• Capable of withstanding significant continuous current and high input energy without failure

Inrush Current Limiters (ICL) Applications

• Switching power supplies
• Uninterruptible power supplies (UPS)
• Industrial inverters
• Variable frequency drives

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific manufacturer part number against official Vishay documentation to confirm the 20-ohm resistance and 6-ampere rating. Ensure the application environment aligns with the 260-joule energy absorption capability. Confirm that the radial PCB mount style matches the target board layout requirements before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component for applications requiring robust protection against high inrush currents in AC-powered systems. The 20-ohm initial resistance effectively limits startup surges, while the 260-joule energy rating ensures durability against repeated stress. Verify that the 6-ampere steady-state current meets the operational load requirements of the specific circuit design.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Vishay Ametherm SL22 series of BigAMP inrush current limiters. These devices are specifically designed for high-performance power electronics where reliable surge suppression is critical. The series offers various resistance and current ratings to suit different power levels and system voltages.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official Vishay datasheets for direct cross-references within the SL22 series. Ensure any substitute maintains equivalent 20-ohm resistance, 6-ampere current handling, and 260-joule energy absorption capabilities.
