■NTC 温度传感器 SENSOR
NTC TEMPERATURE SENSOR
NTC 热敏电阻是一种负温度系数电阻器,其阻值随环境温度的升高而降低,
这种热敏电阻是由 2 种或 4 种铁、镍、钴、锰或铜的金属氧化物经过成型
并在高温下烧结而制得。
NTC thermistor sensor is a Negative Temperature Coefficient Resistor whose resistance changes with
ambient temperature changes. Thermistor comprises 2 or 4 kinds of metal oxides of iron, nickel, cobalt,
manganese and copper, being shaped and sintered at high temperature.
