SL155R006A

Inrush Current Limiters (ICL) Overview

The Vishay Ametherm SL155R006A is a radial lead NTC thermistor in the SL15 series, designed for PCB mounting. It features a nominal resistance of 5 Ohms with a tolerance of ±20%. The component has a steady-state current rating of 6 A and voltage ratings of 115 VAC or 230 VAC. Physical dimensions include a 15 mm diameter and 4.5 mm width, with 0.8 mm leads spaced at 7.8 mm. It holds UL approval.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) technology to limit inrush current
• Provides UL certification for safety compliance
• Supports standard radial through-hole PCB mounting

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against official Vishay documentation to confirm if it denotes a distinct variant from the base SL155R006 model. Confirm that the required lead configuration matches the standard radial style specified for this series. Ensure the application environment remains within the rated voltage and current limits to prevent thermal failure.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 5 Ohm resistance value is required to manage initial surge currents in low-power AC applications. The 6 A steady-state rating suits moderate load requirements. Verify that the 15 mm diameter fits the available board space and that the operating temperature range aligns with the system's thermal profile.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Vishay Ametherm SL15 series of inrush current limiters. These components are specialized NTC thermistors engineered to protect sensitive electronics from high initial charging currents. The series offers various resistance and current ratings to accommodate different power levels while maintaining a compact form factor suitable for dense PCB layouts.

Inrush Current Limiters (ICL) Replacement Considerations

The SL155R006 is a direct electrical equivalent within the same series. Cross-referencing with other manufacturers requires matching the 5 Ohm resistance, 6 A current rating, and 15 mm physical size to ensure functional compatibility.
