Inrush current limiting thermistors are used for protecting the circuit against occasional current spikes significantly higher than normal operating current, which could otherwise damage the equipment. At Rhopoint Nordic we offer a range of current limiting resistors from industry leading manufacturer Ametherm, with various sizes, resistance and maximum steady state current options available. The Ametherm thermistors compare favourably with traditional inrush current limiters, offering lower current density, faster reset time, wider temperature range and virtually no derating.

The AS32 0R530 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 30A (up to +25°C) and a resistance of 0.5Ω ±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.
Typical applications for the AS series include:
