The AS32 10015 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 15A (up to +25°C) and a resistance of 10Ω ±25% (at 25°C). The Ametherm AS series are designed to withstand high steady-state current and input energy. Compared to traditional inrush current limiters, the devices offer lower current density, faster reset times, and a wider temperature range without derating. This lower current density, in combination with a uniform temperature gradient throughout the disc, increases reliability by eliminating hot spots from fatigue. The AS series from Ametherm are suitable for high energy and short term high current applications.
