SL1210006B

Inrush Current Limiters (ICL) Overview

The SL1210006B is a leaded inrush current limiter (ICL) from the Vishay Ametherm SL12 series. It features a negative temperature coefficient (NTC) thermistor with a nominal resistance of 10 Ohms and a tolerance of ±20%. The component is rated for a maximum steady-state current of 6 A and has a physical diameter of 13 mm (0.512 inches). Designed for through-hole mounting, it provides effective circuit protection against high initial surge currents during power-up phases.

Inrush Current Limiters (ICL) Feature Summary

• Provides reliable suppression of high inrush currents during system startup
• Utilizes NTC thermistor technology for automatic resistance adjustment based on temperature
• Supports through-hole mounting for robust mechanical integration

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Industrial automation control systems
• Embedded system power management

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix to ensure correct resistance and current ratings. Confirm availability status as distribution may vary by region. Check datasheet for thermal derating curves and maximum energy absorption limits before finalizing design specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm initial resistance and 6 A continuous current rating are required. Ensure the PCB footprint accommodates the 13 mm diameter body. Consider ambient operating temperatures and peak pulse energy requirements to prevent thermal runaway or permanent damage during repeated surge events.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL12 series of inrush current limiters manufactured by Vishay under the Ametherm brand. These components are specifically engineered for general-purpose circuit protection, offering a balance between surge suppression capability and low steady-state power dissipation compared to fixed resistors.

Inrush Current Limiters (ICL) Replacement Considerations

Compatible substitutes include the SL1210006-B variant. Verify that any replacement maintains the 10 Ohm nominal resistance, ±20% tolerance, and 6 A current handling capacity to ensure equivalent circuit performance.
