SG26T

Inrush Current Limiters (ICL) Overview

The SG26T is a negative temperature coefficient (NTC) thermistor from the Vishay Ametherm Surge-Gard series, designed as an inrush current limiter. It features a radial leaded package with outside kink leads for PCB mounting. The component has a nominal resistance of 5 Ohms at +25°C with a tolerance of 15%. It supports a steady-state current rating of 12A and operates within a voltage range up to 265 VAC. The unit measures 22.86 mm in diameter and functions within a temperature range of 0°C to +65°C.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes NTC thermistor technology to limit high initial charging currents in power circuits.
• Features radial leads with outside kinks for secure through-hole PCB mounting.
• Includes UL approval for compliance with safety standards.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'T' against the official datasheet to confirm lead configuration and packaging details. Ensure the selected variant matches the required 5 Ohm resistance and 12A current rating for the target application. Confirm RoHS compliance status via the manufacturer's documentation before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select the SG26T when a 5 Ohm cold resistance and 12A steady-state current capacity are required. Verify that the 22.86 mm diameter fits the available PCB space. Ensure the operating environment stays within the specified 0°C to +65°C range. Check if the UL approval is necessary for the end-product certification requirements.

Inrush Current Limiters (ICL) Part Context

The SG26T belongs to the Vishay Ametherm Surge-Gard series of inrush current limiters. This family offers various sizes and resistance values to protect electronic equipment from damaging surge currents during power-up. The SG model line is widely used in industrial and commercial power applications requiring reliable current limiting.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference other SG series components with matching 5 Ohm resistance and 12A current ratings. Verify physical dimensions and lead spacing compatibility before substitution. Consult the official datasheet for equivalent part numbers within the Vishay Ametherm portfolio.
