SL1210006

Inrush Current Limiters (ICL) Overview

The SL1210006 is a negative temperature coefficient (NTC) thermistor from the Vishay Ametherm SL12 series, designed as an inrush current limiter. It features a nominal resistance of 10 Ohms with a tolerance of ±20%. The component supports a steady-state current rating of 6 A and has a diameter of 13 mm. It utilizes radial leads for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high initial charging currents during power-up sequences
• Automatically transitions to low-resistance state after thermal activation
• Radial leaded construction facilitates through-hole 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 the specific suffix requirements against the official datasheet to ensure correct lead configuration and voltage ratings. Confirm that the selected variant matches the required steady-state current and resistance specifications for the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 10 Ohm resistance value and 6 A current handling capability. Ensure the 13 mm diameter package fits the available PCB space and that the operating voltage does not exceed the device's rated limits.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL12 series of inrush current limiters manufactured by Vishay Ametherm. These components are specialized NTC thermistors engineered to protect electronic circuits from damage caused by excessive surge currents during initial energization.

Inrush Current Limiters (ICL) Replacement Considerations

The SL1210006B is a documented variant within the same product family. Verify if the 'B' suffix indicates a specific lead kink or packaging difference before substitution.
