薄膜热敏电阻成都国营宏明无线电器材厂最近生产一种薄膜热敏电阻。它是采用高频溅射技术,将半导体热敏材料直接沉积在基体上而制成的。基体可以是玻璃、陶瓷或单晶硅。在小型化特别是微型电路中作晶体管温度补偿元件非常适宜,同时作远红外探测的敏感元件也有独特的优点。主要性能:高温阻值:1000欧～10兆欧温度系数:±2～-6,+10％℃时间常数:1～100毫秒稳定性:1000小时,变化<±1％工作温度:-55℃～+125℃ Thin Film Thermistor Chengdu State-Hongming Radio Equipment Factory recently produced a thin film thermistor. It is the use of high-frequency sputtering technology, the semiconductor thermal material directly deposited on the substrate and made. The substrate can be glass, ceramic or monocrystalline silicon. It is very suitable to make the transistor temperature compensation component in the miniaturization especially the miniature circuit, and the sensitive element that makes the far infrared detection at the same time has unique merit. Main performance: high temperature resistance: 1000 ohm to 10 megohm Temperature coefficient: ± 2 ~ -6, + 10% ℃ Time constant: 1 ~ 100 ms Stability: 1000 hours, change <± 1% Operating temperature: -55 ℃ ~ + 125 ℃
