SL10 2R005-B

Inrush Current Limiters (ICL) Overview

The SL102R005B is a Negative Temperature Coefficient (NTC) thermistor from the Vishay Ametherm SL10 series, designed as an inrush current limiter. It features a nominal resistance of 2 Ohms with a tolerance of ±25% and a steady-state current rating of 5 A. The component has a cylindrical body diameter of 10 mm and utilizes radial leads for PCB mounting. It supports voltage ratings of 115 VAC and 230 VAC.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences to protect downstream components.
• Utilizes NTC thermistor technology where resistance decreases significantly as temperature rises during operation.
• Features a compact 10 mm cylindrical form factor suitable for space-constrained printed circuit board layouts.

Inrush Current Limiters (ICL) Applications

• Protection circuits for switching power supplies
• Inrush current limiting in AC/DC converters
• Surge protection in consumer electronic devices

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm lead configuration and marking details. Ensure the selected variant matches the required thermal characteristics and mechanical dimensions for the target PCB footprint. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 2 Ohm initial resistance and 5 A current rating to match the system's peak inrush requirements. Consider the 10 mm diameter for spatial constraints and verify compatibility with standard radial through-hole assembly processes. Evaluate the thermal environment to ensure the thermistor operates within its specified voltage and current limits during steady state.

Inrush Current Limiters (ICL) Part Context

This device belongs to the Vishay Ametherm SL10 series of inrush current limiters. These components are widely used in electronics to mitigate the stress caused by high initial charging currents. The SL10 series offers various resistance and current combinations to suit different power levels and form factors.

Inrush Current Limiters (ICL) Replacement Considerations

The SL102R005B may be substituted with other Vishay Ametherm parts from the SL10 series that share identical 2 Ohm resistance and 5 A current ratings. Verify mechanical dimensions and lead spacing before replacing with generic equivalents to ensure fit and function.
