Ametherm to Showcase SURGE-GARD™ Inrush Current Limiters and NTC Disc Thermistors at APEC 2014

CARSON CITY, NV--(Marketwired - Mar 11, 2014) - Ametherm today announced that the company will be showcasing selections from its RTI Electronics SURGE-GARD™ line of inrush current limiters and NTC disc thermistors for high-accuracy temperature measurement -- both recently acquired from Measurement Specialties -- at the Applied Power Electronics Conference and Exposition (APEC) 2014, taking place March 16-20 in Fort Worth, Texas.

In booth 1032, Ametherm will be highlighting SURGE-GARD devices that can withstand high steady-state currents from 2 A to 30 A and up to 300 J of input energy. Constructed of specially formulated metal oxide ceramic materials, the thermistors are optimized for a wide variety of applications that require inrush current limiting to reduce circuit failure -- including switching power supplies, AC motors, motor drives, audio amplifiers, and battery chargers. Featured devices offer resistance at 25 °C from 0.5 to 120 ohms, tolerances down to 15 %, and diameters from 10 mm to 32 mm.

NTC disc thermistors on display at APEC 2014 will include devices with diameters from 2.54 mm to 10.2 mm, dissipation constant from 3 mw/°C to 9 mw/°C, and thermal time constant down to 10 s. Offering high-temperature operation to +150 °C and resistance at 25 °C from 4 to 100,000 ohms, the devices provide high stability and maximum sensitivity for temperature measurement, compensation, and control in fan motor controls, fluid levels, and temperature sensors in a wide range of end products.

As the premier event in applied power electronics, APEC focuses on the practical and applied aspects of the power electronics business. More information on the conference and exposition is available at
