Ametherm AS Series Inrush Current Limiters offer thermistor protection for precharge circuits on lithium-ion batteries. With a lower current density, faster reset time, and uniform temperature gradient throughout the disc, there are no hot spots from fatigue. The Ametherm AS Series provides inrush current protection for 250 to 1,000 joules of input energy and allows between 10W to 18W in the 10A to 50A SSI range and up to 900 joules of energy. Ametherm Inrush Current Limiters are designed to protect your components from damaging levels of inrush current at startup.
Lower current density (as compared to traditional types of inrush current limiters)
No hot spots from fatigue, because of lower current density and uniform temperature gradient throughout the disc
Wider temperature range of operation without de-rating
