SL1580002

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL1580002 is an NTC thermistor inrush current limiter belonging to the SL15 series. It features a 15mm disc size and provides a nominal resistance of 80 ohms at 25°C with a tolerance of ±25%. The component supports a maximum steady-state current of 2A up to 65°C and has a recommended energy rating of 45J at 25°C. It is UL approved for use in electronic circuits requiring surge protection.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) technology to limit initial surge currents during power-up
• Provides reliable protection against high inrush currents in electronic equipment
• Features a robust 15mm disc construction suitable for through-hole mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary windings
• Capacitor charging circuits
• Motor drive inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 80-ohm resistance and 2A current rating. Confirm that the 15mm package size fits the intended PCB layout. Ensure compliance with relevant safety standards such as UL approval if required by the final application design specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when circuit design requires limiting inrush current to protect downstream components like rectifiers or capacitors. Consider the 80-ohm cold resistance value and its impact on normal operation. Evaluate the thermal environment to ensure the steady-state current rating remains sufficient under operating conditions.

Inrush Current Limiters (ICL) Part Context

This component is part of the Vishay Ametherm SL15 series of MegaSurge inrush current limiters. These devices are designed specifically for protecting sensitive electronic components from damage caused by high initial current surges during system startup or power restoration events.

Inrush Current Limiters (ICL) Replacement Considerations

Substitute parts must match the 80-ohm resistance, 2A current rating, and 15mm diameter. Verify equivalent energy ratings and safety approvals before implementation.
