SL055R001A

Inrush Current Limiters (ICL) Overview

The SL055R001A is a radial lead NTC thermistor inrush current limiter from the Vishay Ametherm SL05 series. It features a nominal resistance of 5 Ohms with a tolerance of 25%. The component supports a maximum steady-state current of 1 A at temperatures up to 65°C and operates within voltage ratings of 110 VAC to 126 VAC. Physical dimensions include a diameter of 6 mm, width of 3.5 mm, and lead spacing of 5.1 mm. It utilizes radial termination for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) thermistor technology to limit initial surge currents during power-up.
• Designed for radial through-hole PCB mounting with kinked or straight lead options depending on specific variant configuration.
• Provides thermal protection by maintaining low resistance after the initial inrush period has passed.

Inrush Current Limiters (ICL) Applications

• Protection of AC/DC power supplies against high inrush currents
• Surge current limiting in consumer electronic devices
• Input stage protection for small signal transformers

Inrush Current Limiters (ICL) Procurement Notes

Verify the exact lead style and tolerance requirements against the official datasheet before ordering. Confirm that the operating environment does not exceed the maximum steady-state current rating of 1 A at 65°C. Ensure PCB layout accommodates the 5.1 mm lead spacing and 6 mm body diameter. Check for RoHS compliance status if required by your manufacturing standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 5 Ohm cold resistance is required for circuits drawing up to 1 A steady state. Consider the SL05 series for compact applications where a 6 mm diameter fits the board space. Evaluate the thermal dissipation capabilities relative to the ambient temperature to ensure the 1 A rating remains valid under actual operating conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Vishay Ametherm SL05 series of inrush current limiters. The series offers various resistance values and current ratings tailored for different power levels. The SL05 designation indicates a 6 mm diameter form factor, distinguishing it from larger series like SL15 or SL22 which handle higher currents.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 5 Ohm resistance, 1 A current rating, and 6 mm diameter. Verify that alternative NTC thermistors from other manufacturers support the same 110-126 VAC voltage range and radial package dimensions to ensure mechanical compatibility.
