SL1516004

Inrush Current Limiters (ICL) Overview

The SL1516004 is a negative temperature coefficient (NTC) inrush current limiter from the Vishay Ametherm SL15 series. It features a nominal resistance of 16 ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 4.4 A at 25°C and 4.0 A at 65°C. It has a cylindrical body diameter of 15 mm and utilizes radial leads for PCB mounting. The device is rated for voltages up to 230 VAC and offers a recommended energy absorption capacity of 50 J, with an actual energy failure threshold of 100 J.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences
• Features automatic reset capability after thermal cooling cycles
• Constructed with radial leads for standard printed circuit board integration

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific order matches the SL1516004 designation to ensure correct 16-ohm resistance and 4.4 A current rating. Confirm package type and lead configuration align with the target PCB footprint. Check RoHS compliance status if required by project specifications. Ensure storage conditions maintain component integrity prior to assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 16-ohm initial impedance is required to limit surge current. Ensure the application's steady-state current does not exceed 4.4 A at ambient temperatures up to 25°C. Verify that the expected surge energy remains within the 50 J recommendation to prevent thermal damage. Consider the 15 mm diameter for adequate spacing on the circuit board.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL15 series of inrush current limiters manufactured by Vishay Ametherm. The series provides various resistance and current ratings for different power levels. These components are designed to protect sensitive electronic circuits from damage caused by high initial charging currents.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 16-ohm resistance, 4.4 A current rating, and 15 mm diameter. Cross-reference with other manufacturers offering equivalent NTC thermistors in the SL15 form factor.
