SL082R503A

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL082R503A is an NTC inrush current limiter (ICL) from the SL08 series. It features a nominal resistance of 2.5 Ohms with a tolerance of ±25%. The component has a steady-state current rating of 3 A and a maximum diameter of 0.315 inches (8.0 mm). It is designed to withstand 10 Joules of inrush energy, providing effective protection against high initial currents in electronic circuits.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) thermistor technology to dynamically limit inrush current during power-up.
• Provides robust protection by absorbing up to 10 Joules of inrush energy to safeguard sensitive downstream components.

Inrush Current Limiters (ICL) Applications

• Protection for switching power supplies
• Inrush current limiting in AC/DC converters
• Surge suppression in general electronic equipment

Inrush Current Limiters (ICL) Procurement Notes

Verify specific ordering suffixes and availability directly with the manufacturer or authorized distributors, as supply status may vary. Confirm that the selected part number matches the required electrical specifications for your application before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its 2.5 Ohm resistance and 3 A current rating to match circuit requirements. Ensure the 10 Joule energy absorption capability is sufficient for the expected surge conditions in the target application environment.

Inrush Current Limiters (ICL) Part Context

This device belongs to the Vishay Ametherm SL08 series of inrush current limiters. These components are specifically engineered for through-hole mounting and offer reliable performance in compact form factors suitable for various consumer and industrial electronics applications.

Inrush Current Limiters (ICL) Replacement Considerations
