SL082R503

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL082R503 is a radial leaded inrush current limiter (ICL) designed for PCB mounting. It features a nominal resistance of 2.5 Ohms with a tolerance of ±25% and a maximum steady-state current rating of 3 A at 65°C. The component has an 8 mm diameter, 16 mm length, and 7.8 mm lead spacing. It withstands up to 10 Joules of inrush energy and operates within a temperature range of -40°C to +125°C.

Inrush Current Limiters (ICL) Feature Summary

• Provides high inrush current limiting capability to protect downstream components during power-up.
• Utilizes NTC thermistor technology that automatically reduces resistance as temperature rises.
• Designed for robust performance under repeated surge conditions without degradation.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection
