AMWEI Thermistor Co., Ltd. specializes in the research, development and manufacture of PTC and NTC thermistor products. PTC thermistor application covers overcurrent & overload protection, telecom, lighting switching, motor starting, temperature protection, self-regulation heating, degaussing, and NTC thermistor application covers inrush current limiter, temperature measurement, temperature compensation, temperature control, 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. ISO9001:2000 certified in 2003.
