Ametherm's new series of inrush current limiting NTC thermistors are designed to withstand high input energy from 500 J to 900 J and steady-state currents from 10 A to 50 A. Offering a rugged design, MS35 series devices are optimized for high-power applications, including solar inverters, battery chargers, and DC/DC converters. The MS35 series consists of seven thermistors featuring resistance from 0.5 Ω to 20 Ω, dissipation constants from 78 mw/ °C to 102.45 mw/ °C, and thermal time constants from 65 s to 240 s. The devices can handle body temperatures up to 235 °C at 100% of their maximum current rating, and offer maximum capacitance from 1000  µF to 1800  µF at 680 VAC. Featuring diameters of 37mm and 38mm and thickness down to 6.50mm, the thermistors handle the same amount of energy as power resistors in a smaller package, saving valuable circuit board space. In addition, they provide simple one-component alternatives to using power resistors with timers and relays, reducing costs and simplifying designs.
