SL0812101AT

Inrush Current Limiters (ICL) Overview

The SL0812101AT is an NTC thermistor inrush current limiter from the Vishay Ametherm SL08 series. It features a nominal resistance of 120 Ohms with a tolerance of ±20% and a steady-state current rating of 1 A. The component has an 8 mm diameter body with kinked radial leads spaced at 5 mm. It supports voltage ratings up to 680 VAC and withstands 10 Joules of inrush energy. Operating within standard PCB mount configurations, it utilizes bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) thermistor technology for effective surge suppression
• Features kinked radial leads designed for secure PCB mounting in space-constrained environments
• Capable of absorbing high inrush energy surges to protect downstream circuit components

Inrush Current Limiters (ICL) Applications

• Power supply input stages requiring surge protection
• Transformer primary side inrush current limiting
• Space-sensitive electronic assemblies needing compact footprint solutions

Inrush Current Limiters (ICL) Procurement Notes

Verify that the AT suffix corresponds to the specific lead configuration or marking required for your assembly process. Confirm the 120 Ohm resistance value aligns with your circuit's thermal design calculations. Ensure the 1 A steady-state current rating exceeds your maximum operating load. Check compatibility with your PCB hole spacing for the 5 mm lead pitch. Validate that the 8 mm diameter fits within your mechanical enclosure constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when board space is limited due to its compact 8 mm diameter profile. Choose based on the 120 Ohm initial resistance to achieve desired inrush current levels. Ensure the 1 A current rating meets peak operational demands without overheating. Consider the kinked lead style for automated placement if applicable. Verify voltage ratings match the system's AC line requirements.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL08 series, which is specifically engineered for applications where physical board space is restricted. The series provides reliable inrush current limiting using NTC thermistors. It serves as a critical protection element in power electronics, preventing damage from capacitive charging currents during startup phases.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include the SL0812101A variant, which shares identical electrical specifications but may differ in lead form or packaging. Cross-reference the SL05 series only if reduced dimensions are acceptable despite lower current handling capabilities.
