The MS35 1R040 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 40A (up to +25°C) and a resistance of 1Ω ±25% (at 25°C). Ametherm’s MegaSurge™ series of inrush current limiting thermistors are capable of handling up to 900 joules of energy and 50 amperes of steady state current. These power thermistors are rugged and built to last even in the most demanding high power applications. The Ametherm MS35 devices play a key role in alternative energy applications by avoiding current spikes in the power generated by wind turbines, solar panels, and other sources as it’s fed into batteries, inverters, and other energy storage components. These MegaSurge™ devices are also used to regulate the release of battery energy in electric vehicles and in pre-charge circuits for many different types of battery chargers.
