SL085R003A

Inrush Current Limiters (ICL) Overview

The SL085R003A is an inrush current limiter from the Vishay Ametherm SL08 series. It features a nominal resistance of 5 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 3 A at 25°C. It has a cylindrical body diameter of 8 mm and utilizes radial leads for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Limits high initial surge currents during power-up to protect downstream components
• Provides automatic reset functionality after thermal stabilization
• Designed for reliable operation in standard through-hole PCB assemblies

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official datasheet to confirm exact electrical tolerances and mechanical dimensions. Ensure the selected variant matches the required steady-state current rating of 3 A and resistance value of 5 Ohms for the target circuit design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 5 Ohm resistance and 3 A continuous current capacity are required for inrush limiting. Consider the 8 mm diameter for available board space and verify that the radial lead configuration aligns with the chosen PCB footprint and assembly process.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 series of ceramic inrush current limiters. These devices utilize negative temperature coefficient characteristics to reduce resistance as they heat up, allowing normal operating current to flow freely after the initial surge phase.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the official Vishay Ametherm cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on similar resistance values alone; verify current ratings and physical dimensions.
