Ametherm on June 7, 2017, announced a new circuit protection thermistor that offers the industry’s smallest diameter for a UL-approved device with a maximum continuous current rating of 6.0 A and energy rating of 40 J.
Previously, designers had to rely on devices with larger diameters from 15.0 mm to 25.0 mm to achieve the high current and energy ratings of the new SL12 10006. Offering a radial lead package with a maximum diameter of only 13.0 mm and height profile of 5.5 mm, the device released saves board space, lowers costs, limits excess circuit board heat, and enables faster reset times.
The small size and high current rating of the SL12 10006 make it ideal for appliance motors and fractional horsepower motor drives, 300 W to 600 W switch mode power supplies, LED drivers, and small inverters for recreational vehicles. The device features a resistance of 10.0 Ω, dissipation constant of 13.5 mW/°C, and thermal time constant of 42 s. The thermistor can handle body temperatures up to 210 °C at 100% of its maximum current rating.
The SL12 10006 circuit protection thermistor is available direct or through distributors such as Digi-Key and Mouser. Samples and production quantities of the devices are available now, with factory lead times of eight weeks.
