表面贴装高精度大功率N TC热敏电阻的研发

摘要

表面电极式片式化设计和薄而致密玻璃表面封装技术，增大了元件的耗散系数，增强了片式大功率型N TC热敏电阻的耐恶劣环境（潮气、盐雾等）能力；宽长条划切工艺可高精度精确调节电阻值，提高了大功率N TC热敏电阻器的电气性能。%Using chip design technology of surface electrode and packaging technology with thin and dense surface glass increase the dissipation constant of element and enhance the capacity of resistance to harsh environment (moisture, salt spray, and so on) of high power chip NTC thermistor. Wide strip cutting process can adjust the resistance value accurately, and enhance electrical properties of high power chip NTC thermistor.
