SG308C001

Inrush Current Limiters (ICL) Overview

The SG308C001 is a radial leaded inrush current limiter (ICL) from the SURGE-GARD series, manufactured by Vishay Ametherm. It utilizes an NTC thermistor design to suppress high initial charging currents in electronic circuits. The component features a nominal resistance of 4 Ohms with a tolerance of ±15% at 25°C. It supports a maximum continuous current rating of 8 Amps and has a physical diameter of 15.24 mm (0.600 inches).

Inrush Current Limiters (ICL) Feature Summary

• Suppresses high inrush currents during power-up sequences.
• Utilizes negative temperature coefficient thermistor technology.
• Designed for robust transient protection in power systems.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct resistance and current ratings. Confirm that the radial package style matches the target PCB layout requirements. Check for RoHS compliance status if required by the manufacturing process. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state resistance and peak current handling capabilities. Ensure the operating environment stays within the specified thermal limits. Verify that the radial lead spacing accommodates the available board space. Consider the self-heating characteristics under continuous load conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SG308 series of inrush current limiters. It is designed for general-purpose power electronics applications where controlling surge currents is critical. The SURGE-GARD brand indicates specialized protection components.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 4 Ohm resistance, 8A current rating, and 15.24mm diameter. Verify equivalent thermal characteristics and package dimensions before substitution.
