SG64

Inrush Current Limiters (ICL) Overview

The SG64 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 features a nominal resistance of 7 Ohms and a steady-state current rating of 10 A at 265 VAC. The component has a tolerance of ±15%, an outside kinked lead configuration, and operates within a temperature range of 0°C to +65°C. It carries UL approval.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to limit initial surge currents during power-up
• Features outside kinked radial leads for secure PCB mounting
• Complies with UL safety standards for electrical components

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Electronic equipment protection circuits
• Consumer appliance power inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct lead type and packaging configuration. Confirm that the voltage and current ratings align with the target circuit requirements before procurement. Check for RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 7 Ohm resistance and 10 A current handling capability. Ensure the PCB layout accommodates the radial lead spacing and physical dimensions. Consider thermal management needs as the device dissipates energy during the inrush period.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SG series of inrush current limiters manufactured by Vishay / Ametherm. These components are specifically engineered to protect sensitive electronic circuits from high initial charging currents when connected to a power source.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 7 Ohm resistance, 10 A current rating, and radial package. Verify equivalent voltage ratings and thermal characteristics before substitution.
