The SG170 is an inrush current limiter (ICL) manufactured by Ametherm Inc. It belongs to the SURGE-GARD family of NTC thermistors designed to suppress high inrush current surges in power supply circuits.
Key specifications include a nominal resistance of 4 Ohms at 25°C and a steady state current rating of 8A. The device has a diameter of 15.24mm and is through-hole mountable.
NTC thermistors like the SG170 exhibit a decrease in resistance as temperature increases, making them ideal for limiting the initial surge current when power is first applied. This helps protect downstream components such as diode bridge rectifiers and reduces stress on fuses.
