SG16

Inrush Current Limiters (ICL) Overview

The SG16 is a negative temperature coefficient (NTC) thermistor inrush current limiter from the Vishay Ametherm SURGE-GARD series. Designed for PCB mounting with radial leads, it provides surge protection in electronic circuits. The component features a nominal resistance of 60 Ohms and supports a steady-state current rating of 1.5 A at a maximum voltage of 265 VAC. It has a tolerance of 20%, a diameter of 0.6 inches, and operates within a temperature range of 0°C to +65°C.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to limit initial charging currents
• Radial leaded construction facilitates through-hole PCB integration
• Compliant with UL safety standards for circuit protection

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• Capacitor bank charging circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct lead configuration and packaging. Confirm that the selected variant matches the required 60 Ohm resistance and 1.5 Ampere current rating for the target application. Cross-reference the package dimensions with the PCB footprint to guarantee mechanical compatibility during assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 60 Ohm cold resistance value which determines the peak inrush current limitation capability. Ensure the 1.5 A continuous current rating exceeds the circuit's operating load. Verify the 265 VAC voltage rating aligns with the system's line voltage requirements and confirm the 0.31-inch lead spacing fits the board layout constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SG series of SURGE-GARD inrush current limiters manufactured by Vishay Ametherm. These components are engineered to protect sensitive electronics from high transient currents during power-up. The series offers various resistance and current ratings to suit different power levels while maintaining standard radial leaded packages for easy installation.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Vishay Ametherm parts within the SG series that match the 60 Ohm resistance and 1.5 A current specifications. Equivalent components from other manufacturers must be evaluated for matching electrical parameters, thermal characteristics, and physical dimensions to ensure functional interchangeability.
