SG313C005

Inrush Current Limiters (ICL) Overview

The SG313C005 is a custom inrush current limiter (ICL) manufactured by Vishay Ametherm. It features a nominal resistance of 10 Ohms with a tolerance of ±15%. The device supports a maximum steady-state current rating of 3 A. Physical dimensions include a diameter of 0.500 inches (12.70 mm). The component utilizes radial leads for PCB mounting and is designed to limit surge currents during power-up sequences.

Inrush Current Limiters (ICL) Feature Summary

• Provides high initial resistance to restrict inrush current flow upon circuit energization
• Automatically transitions to low-resistance state as temperature increases during operation
• Radial lead configuration facilitates through-hole printed circuit board installation

Inrush Current Limiters (ICL) Applications

• Power supply input stages requiring surge protection
• Transformer primary circuits limiting magnetizing inrush
• Capacitive load charging control in electronic equipment

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific custom designation 'SG313' against official Vishay Ametherm documentation, as standard series typically follow different nomenclature. Confirm that the 10 Ohm resistance and 3 A current ratings align precisely with the target application's thermal and electrical requirements. Ensure the radial lead spacing matches the PCB footprint design before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a fixed 10 Ohm initial impedance is required for specific surge suppression needs. The 3 A current rating dictates suitability for moderate-power applications. Consider the physical size constraints due to the 12.70 mm diameter. Validate that the custom part number corresponds to the exact electrical specifications needed rather than assuming generic family characteristics.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Vishay Ametherm inrush current limiter portfolio, utilizing negative temperature coefficient thermistor technology. These devices are engineered to protect sensitive electronic components from high transient currents. The SG313C005 represents a specialized variant within this category, tailored for specific industrial or commercial power management designs requiring precise surge limitation.
