| | AMWEI Thermistor Co., Ltd. (www.amwei.com), design and manufacture through hole and SMD PTC & NTC thermistors (THERMally sensitive resistors) and temperature sensors probe. PTC (Positive Temperature Coefficient) thermistor application covers over-current & overload protection, telecom, lighting switching, motor starting, temperature sensing & protection, self-regulation heating, linear PTC thermistor, silicon temperature sensor. NTC (Negative Temperature Coefficient) thermistor application covers power thermistor for inrush current suppressing limiting, NTC thermistor for temperature measurement, indicator, temperature compensation, temperature control, in either radial leaded, axial leaded or surface mount configuration. Can also make custom thermistors assemblies and temperature probes, housed in either stainless steel, copper, plastic, teflon, aluminum, epoxy and heat shrinkable tubing, such as air/gas temperature sensors, surface temperature sensors and immersion temperature sensors, etc.
The 2 founders of AMWEI came from Nonmetal Material Research Institute of Huazhong University of Science and Technology, once as a visiting scholar in Japan in late 1980, and took charge of Chinese first imported PTC production line. Thorough successive hard work of a group of specialists in ceramic sensitive material, welding technology, packaging technology, we own core know-how in powder formula and key production technics. Our NTC thermistor features with high accuracy, fast response and long time stability. PTC thermistor switch life and voltage withstanding capacity is leading in China.
AMWEI PTC R&D now aims at low resistivity and miniaturization.
We maintain the highest quality standards through continuous employee training, rigorous internal auditing. We take continuous improvement as a primary business objective. SPC, MSA, 6-Sigma techniques are being applied throughout the manufacturing process in an endless loop of quality improvement.
AMWEI PTC and NTC thermistor has been widely applied in the field of telecom & network, HVAC & R，home electric appliance, white goods, food service, consumer electronics, lighting, office automation equipment, medical, automotive, consumer electronics, meter & instrumentation, data logger, power supply and transformer, industrial process control etc.
HVAC applications include indoor/outdoor air temperature, duct air temperature & water temperature.
Thermistor sensors play a vital part in the efficiency of white goods by measuring and controlling the temperature of water, steam, air, food, as well as the electronic circuitry.
Thermistors can be found all around the home in washing machines, dishwashers, cookers, microwave ovens, irons, toasters, refrigerators and deep freezers.
