| Abstract: | ELECTRONIC COMPONENTS & MATERIALS(China) ,Vol.18,No.5,P.11 12(Oct.1999).In Chinese. The low resistance PTC thermistor for over current protection in communication equipment is studied.The results show that the electrical properties are influenced by TiO 2 particle size,technological parameters,metal electrodes,package type ,etc.The contradiction between fine crystalline structure and low resistance is resolved by correctly choosing the above parameters.(3 refs.) |
