SL2220005ATS

Inrush Current Limiters (ICL) Overview

The SL2220005ATS is a negative temperature coefficient (NTC) thermistor inrush current limiter from the Vishay Ametherm SL22 series. Designed for through-hole mounting, this component features a nominal resistance of 20 Ohms with a tolerance of 20%. It supports a steady-state current rating of 5 Amps and utilizes a 22 mm disc diameter. The device employs radial leads with a kinked configuration to facilitate secure PCB installation.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to provide high initial resistance that decreases as temperature rises during operation.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Capacitor charging control

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix ATS against the manufacturer's official datasheet to confirm if it denotes a custom specification or standard packaging variation. Ensure the selected variant matches the required 20 Ohm resistance and 5A current rating for the target application circuit design.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 22 mm form factor is required for thermal management. Confirm that the 20 Ohm cold resistance aligns with the system's peak inrush current limitations. Validate that the 5A steady-state rating exceeds the maximum operating current of the load.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of inrush current limiters, characterized by a 22 mm disc size. It serves as a protective element within electronic power systems, distinct from other series like SL12 or SL15 which offer different physical dimensions and electrical ratings.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with SL2220005B for standard equivalents. Verify lead configuration compatibility, as the ATS suffix may indicate specific mechanical requirements compared to standard bulk packaging variants.
