SL22 40005-A

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL2240005-A is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter. It features a radial leaded package with a 22 mm diameter body and a nominal resistance of 40 Ohms at 25°C, with a tolerance of ±20%. The component supports a maximum steady-state current of 5 A up to 65°C and withstands voltages up to 265 VAC. It has a maximum recommended energy rating of 63 Joules and utilizes M-type material for beta and curve characteristics.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation against official documentation, as standard listings may not explicitly include the trailing character. Confirm that the required voltage rating and energy absorption capabilities align with the target circuit design parameters before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 40 Ohm resistance value and 5 A current handling capacity. Ensure the application environment does not exceed the 265 VAC limit or the 63 Joule energy rating. Consider thermal derating requirements if operating temperatures approach the upper limits.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of inrush current limiters from Vishay Ametherm. The series provides various resistance and current combinations within a standardized 22 mm form factor, allowing designers to scale protection levels across different power supply architectures while maintaining consistent mechanical footprint.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other Vishay Ametherm SL22 variants such as SL2240005 for identical specifications. Verify that any substitute maintains the same 40 Ohm resistance, 5 A rating, and 22 mm diameter to ensure mechanical and electrical compatibility.
