SL054R002

Inrush Current Limiters (ICL) Overview

The SL054R002 is a negative temperature coefficient (NTC) thermistor inrush current limiter from the Vishay Ametherm SL05 series. It features a nominal resistance of 4 Ohms with a tolerance of ±20% at 25°C and supports a maximum steady-state current of 2.0 A up to 65°C. The component has a beta value of 3000 ± 5%. Its physical dimensions include a diameter of 5.5 mm, designed for PCB mounting applications.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to limit high initial charging currents in electronic circuits.
• Provides automatic resistance reduction as the device heats up during normal operation.
• Designed for radial leaded PCB mounting with compact physical dimensions.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• General electronic equipment requiring surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify availability through authorized distributors as stock status may be restricted. Confirm that the specific package type and lead configuration match the target PCB footprint requirements. Ensure the operating environment temperature does not exceed the specified limits for the rated steady-state current.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 4 Ohm resistance value and 2.0 A current rating. Consider the 5.5 mm diameter for spatial constraints on the printed circuit board. Verify compatibility with the system's voltage ratings and thermal management needs for continuous operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL05 series of inrush current limiters manufactured by Vishay Ametherm. The series offers various resistance and current ratings tailored for different power levels. These components are widely used for protecting sensitive electronics from damage caused by high inrush currents during power-up events.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official datasheets for direct substitutes within the SL05 series or other Vishay Ametherm NTC thermistors with matching electrical parameters and physical dimensions. Ensure any replacement maintains the same beta value and steady-state current capabilities.
