SG165R008S

Inrush Current Limiters (ICL) Overview

The SG165R008S is an NTC thermistor inrush current limiter from the Vishay Ametherm SG series. It features a nominal resistance of 5 Ohms with a tolerance of ±20% and supports a steady-state current rating of 8 A. The component is designed for AC voltage ratings of 115 VAC and 230 VAC. It utilizes a radial leaded package with a kinked lead configuration, measuring 15.24 mm (0.600 inches) in diameter. The unit weighs approximately 3.276 g and is intended for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) technology to limit initial surge currents during power-up.
• Features a robust radial kinked lead design suitable for through-hole PCB mounting.
• Provides stable performance across standard AC line voltages including 115 VAC and 230 VAC.

Inrush Current Limiters (ICL) Applications

• Protection of electronic circuits against high inrush currents
• Power supply input stages
• Consumer electronics AC mains interfaces

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'S' corresponds to the kinked lead configuration required for your assembly process. Confirm that the 8 A steady-state current rating aligns with your circuit's operational requirements. Ensure compatibility with 115 VAC or 230 VAC systems as specified. Check RoHS compliance status if environmental regulations apply to your manufacturing location.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 5 Ohm resistance value is appropriate for limiting surge current without excessive power dissipation during normal operation. The 8 A rating suits moderate power applications. Consider the 15.24 mm diameter for available board space. The kinked lead style facilitates automated insertion or manual placement depending on production needs.
