SL1580003

Inrush Current Limiters (ICL) Overview

The SL1580003 is an NTC thermistor inrush current limiter from the Vishay Ametherm SL15 series. It features a nominal resistance of 80 Ohms at 25°C with a tolerance of ±25%. The device supports a maximum steady-state current of 3.0 A up to 65°C ambient temperature. It is designed for applications requiring surge protection and power supply stabilization.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting to protect sensitive electronic components during power-up.
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature increases.
• Offers reliable performance in safeguarding electrical devices against damaging power surges.

Inrush Current Limiters (ICL) Applications

• Switching power supplies
• Uninterruptible power supplies (UPS)
• Industrial inverters

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific resistance value and current rating against your circuit requirements before ordering. Confirm that the 80 Ohm nominal resistance and 3.0 A steady-state current are suitable for your application's peak load conditions. Ensure compatibility with the SL15 series form factor if replacing existing components.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a compact inrush current limiter with 80 Ohm initial resistance is required. Consider the 3.0 A current limit for moderate power applications. Evaluate thermal management needs, as the device operates effectively up to 65°C for its rated current. Compare with other SL15 variants if different resistance or current ratings are needed.

Inrush Current Limiters (ICL) Part Context

The SL1580003 belongs to the Vishay Ametherm SL15 series of NTC thermistors. This series is widely used for inrush current limiting in various electronic systems. The SL15 series offers a range of resistance values and current ratings to suit different power levels and circuit designs.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes within the SL15 series include parts with similar resistance and current ratings, such as the SL1547003 for lower resistance applications. Verify that any replacement maintains the same package size and thermal characteristics to ensure proper fit and function.
