SL1012101

Inrush Current Limiters (ICL) Overview

The SL1012101 is a leaded inrush current limiter from the Vishay Ametherm SL10 series. It features a nominal resistance of 120 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 1 Ampere at temperatures up to 65°C. Its cylindrical body measures 10mm in diameter, designed for through-hole mounting on printed circuit boards.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high initial charging currents during power-up sequences
• Automatically transitions to low-resistance state after thermal activation
• UL approved for enhanced safety compliance in electronic assemblies

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 and physical dimensions against the official datasheet before integration. Confirm that the 1A steady-state rating aligns with your operational thermal environment. Ensure the 120 Ohm initial resistance meets your circuit's surge suppression requirements without causing excessive voltage drop during normal operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 120 Ohm initial impedance is required to limit peak inrush currents. The 1A current rating defines the continuous operating limit. Consider the 10mm body size for available PCB real estate. Evaluate the thermal dissipation constant to ensure reliable performance under repeated surge conditions within the specified temperature range.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of ceramic inrush current limiters. These components are engineered to protect sensitive electronic components from damage caused by high transient currents. The series offers various resistance and current combinations to suit different power handling needs across industrial and consumer electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other Vishay Ametherm SL10 variants or equivalent NTC thermistors from manufacturers like EPCOS or Murata. Ensure substitute parts match the 120 Ohm resistance, 1A current rating, and 10mm form factor for direct compatibility.
