Ametherm today announced a new series of inrush current limiting NTC thermistors designed to withstand high input energy of 1200 J and steady-state currents from 50.0 to 80.0A at 680V. Offered in DIN-rail-mountable packages, MM35-DIN series devices are optimized for power distribution in high-power industrial and green energy applications including variable-frequency motor drives, transformers, wind turbines, large inverters, and single- and three-phase motors.
MM35-DIN series thermistors are available direct or through Digi-Key and Mouser. Samples and production quantities are available now, with factory lead times of six weeks.
The MM35-DIN series consists of four thermistors featuring resistance at 25°C from 0.2 to 1.5Ω, a maximum power of 38.4W, and thermal time constants of less than 300s. The devices feature diameters of 68.0 mm with a thickness of 8.5 mm and 9.5 mm.
The space and cost-saving thermistors provide simple one-component alternatives to using power resistors with relays or MOSFETs, greatly simplifying designs. For easy installation, the devices are designed for use with a DIN block. This allows for mounting within a power control box using only a screwdriver.
