At APEC 2018, Ametherm will be showcasing a wide range of its leading NTC and PTC inrush current limiters for reliable circuit protection and NTC thermistor sensors for high-accuracy temperature compensation and measurement. Made in the U.S.A., Ametherm’s products are recognized by Underwriters Laboratories (UL) and the Canadian Standards Association (CSA International) for ensured safety, and many are RoHS-2-certified. Ametherm products are available directly from Ametherm or through distributors such as Digi-Key and Mouser.

Products on Display at APEC 2018

MS35 Series of Rugged NTC Thermistors
Optimized for applications such as wind turbines, solar power inverters, battery chargers and DC/DC converters, the MS35 series is designed to withstand high input energy from 500 J to 750 J and steady-state current from 10 A to 50 A. These devices offer resistance at 25 °C from 0.5 Ω to 20 Ω and thermal time constants from 65 s to 240 s. Featuring a diameter of 38 mm and thickness less than 10 mm, these thermistors do the same job as a power resistor and relay, yet in a smaller single-part alternative, saving valuable circuit board space.
