SL1580001

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1580001 is a negative temperature coefficient (NTC) inrush current limiter belonging to the SL15 series. It features a nominal resistance of 8 Ohms with a tolerance of ±20%. The component is rated for a maximum steady-state current of 1 Ampere at 25°C ambient temperature. Designed for through-hole mounting, it utilizes axial leads and is housed in a compact cylindrical package measuring 0.315 inches (8 mm) in diameter.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Features low steady-state resistance to minimize power loss during normal operation
• Designed for reliable performance in space-constrained circuit board layouts
